--- Comment #4 from Ben Anderson roothorick@new.rr.com 2009-05-05 18:22:29 --- The obvious workaround, installing to an ext2 partition and copying over, doesn't work, at least in the case of Shaiya. The updater fails with a cryptic "Extraction failed" message and trying to run the game directly only calls the updater. Running it from the ext2 volume allows it to progress to the current GameGuard-related brick wall. Apparently IS isn't the only victim of this bug...
