PSO2 Update: Hard Drive Wiping Bug

After the update that was distributed on September 4th, 2013, some players reported seeing files wiped from their hard drives in folders that were completely unrelated to PSO2. Upon discovering this issue, they immediately cancelled distributing the update and are now trying to fix the program that caused this issue.
