  1. Still don't get it. Still no Patch announced by Tweaker (So I got Error 640). What am I supposed to do? Wait so more or try the official launcher? .__.

    1. Mine didn't update either. There are, however, instructions on the right side of the tweaker (the plugin status thing) telling people to: click on the orb > troubleshoot > fix PSO2 EXEs. It did the job for me.

    2. Well, I've seen this message but had to go somewhere. When I returned some hours later, it had desappeared… Anyway I tried but for only result I had a error message of GG, and when I relaunched the Tweaker it said "Your GN Field seems to be outdated or corruped, redownload… Redowloading… Redowloading… Redowloading… Redownloading…" But nothing happened so I returned the PC to a previous point after last Patch.

      I wanted to try the Old Method but it seems pretty long so I canceled. Plus the number of files it checks is less than the content of my PSO2_bin…

      I'll wait a little more just in case of and retry Old Method… If it still doesn't work, I have no luck and'll have to use the Official, right…? ._.

    3. Pretty sure Old Method is the direct equivalent of the official-launcher update check. If not the exact same thing merely run from the Tweaker.

      Incidentally, note that PSO2_bin also holds the original backups for the files replaced by the EN patches.

    4. I had that same problem of GN field continually redownloading. Simply Right Click Delete the entire Tweaker Folder containing the tweaker itself, the GN field, the error text files, everything except of course the PSO2.

      Then do as i did and go to ARks layer's website and download a brand new tweaker fresh install and run it again. I was up in minutes. Just run the tweaker installer fresh you should be fine.

    5. Open task manager for this and end the process of GNFIeld, then reload the Tweaker, when GN Field says it's corrupted or outdated its 1 of 2 things, 1 being firewall protection and 2 (most common problem) the previous GN Field when you started tweaker says it closed but didn't actually close, so force end the process yourself should fix this problem.

    6. Uh, honestly I don't understand… I launched the Tweaker that, this time, told there was a new update for it. I said "yes" but it didn't do anything. Maybe I should wait some more, as it didn't even tell it yesterday…

      I'll try the Old Method before anyway but I'll think of your method. I was wondering if deleting just GNF was enough to let Tweaker redownload it but if it needs the full folder to…

  2. Manually. it didnt download the update for me automatically either. But when i choose the 'Search for update (Old method) in the Orb menu it downloaded the update for me. Been playing for awhile now.

  3. Ok, finally did the Old Method and all went fine (The "Updater" prog. didn't seem to really download but maybe we don't care). Don't know if it's always so long but it took over 50min..

    Anyway now, I guess I don't have other choices than to update with Old Method in the future Patchs, right?

    Thanks everyone for your help. 😉 (And yeah Old Method is nearly like the JP thing, cause both check files the same way I think.)

  4. Uh… I'm really lost.
    After ending the patch yesterday I had two crashes… And today a lot of errors I don't understand. It just crashed once in the Op logos everytime. I made a System Restauration I made just after ending patch and I could play two hours without a problem and now we on the same point again. Even had a NP1008 error once. I tried checking for Instalment (No problem, it seems), redownloading EXEs but no use.
    … I'm lost here. I'm hesitating of using the Official Launcher to let it check (It would certainly correct errors if it's not from the PC… I guess) or even returning to my laptop and update everything (Haven't been done since late may)… But I hope someone will have clues to help. I'm sure restoring PC before the Patch (That will erase it) and retrying can be good too but I prefer some ideas.

    Real thanks to anyone that can help…

    1. delete GG folder if not working just run original JP launcher after that please backup your original pso2 folder man, to external hdd or flashdrive or you laptop, burn into dvd etc. good luck.

    2. Seems like a really critical problem when I read you… ._. But launching PSO2 after deleting GG, won't it just make it re-download automatically (And in that case I can ask Tweaker to do it)?

      Somehow I'm wondering if it's not the Update not working as it should… I'd be curious to try again if New Method works with it (Honestly didn't have any problem with it before this time, never.).

    3. …reverting to whatchamacallem, system snapshot sounds like ludicrous overkill and in any case won't do anything Old Method/official-launcher filecheck don't.

      GG is bullshit and sometimes starts failing weirdly for no reason, which also can throw off the black magic Tweaker uses to circumvent it. Deleting its files so you get a fresh set usually puts paid to that – Tweaker's "fix GG problems" does pretty much exactly this, it just saves you the work of deleting the folder manually.

    4. I didn't try anything yet but I'll proceed step by steps following your advices.

      Try without doing anything (We never know)
      Try redowloading GG with Tweaker
      Erase GN Field and let it redownload
      Restoring the PC to a point where it works and try all steps
      Try JP launcher
      … Wait the next patch and hoping if will fix if nothing works
      … Uninstalling everything and reinstalling…

      I have a lot of free time today… >_>

    5. Uh, just to be sure… I tried updating with my laptop just by curiosity. For the first time, when I updated the Tweaker, Avast told me it wanted to analyze pso2tweakerupdater.exe 'cause it's a possiby nocive program. It never did that with the PC I'm talking about here but I'm wondering if the cause can't be this stupid antivirus.

      Did anyone else had problems with it lately? I'm hesitating to desativate it (Won't have any effect I guess) or even deinstalling it but I better be sure.

    6. Huh. So if you're a PC supergenius, answer me:

      I've made Tweaker updating GG, didn't work.
      Put the Tweaker folder as Exception in Avast, didn't work.
      Try checking for eventual Old/Missing Files, didn't work.
      Tried official thing: Didn't launch and just told I needed to update of I don't know what.
      Deleted GNF to have a new one: Didn't work.
      Everything worked before the last Patch I had to do with Old Method (As I had no problem at all with New Method since then).
      It always crashes between entry logos, and with some luck like my first try tpday, choosing character.

      It looks like if something was wrong somewhere in the folder but Tweaker can't find what, as all seems OK.

      I can imagine it's the PC then but I don't use it for anything else than PSO2, Bumped and some Tôhô sometimes.

      I'm curious about your opinion of this. It's nice to tell things on people when we can't think of something better. (But I have ideads of the next steps to try anyway)

  5. Hello, how do I get AC? I'm from Australia, and I cant use Google Play Cards as it wont be accepted on my PSO2ES(Even with Tweaker) and my Debit/Credit card is linked to my mother's bank account of which she controls it tightly. Any ideas to solve my dilemma?

    1. Well Arks Layer used to have a system that let you buy Webmoney through them that you could then use in turn at the PSO2 site to buy AC. So I guess try looking for a place that lets you do something like that.

  6. open official launcher.Use the bottom Icon and it will revert to vanilla Pso2 and fix gameguard issues. it takes 20 something minutes and you dont have to mess around with the tweaker.Delete old tweaker folder and redownload a new one at
