Come on, Toxic already voted for me.
Download the installer for the latest version. As long as it's just a few small files, we can send you anything that thinks it's corrupted.Yeah and that's a clean install, hence the "sisi" folder. I don't WTF is up, but it hasn't been right since Apocrypha.
It's entirely possible CRC failures are usually consistent with drive failures (be it the drive, the cabling, etc), but it's also sometimes consistent with memory errors. Something may be occurring in the RAM during the calculation.Gonna try another install, but on C: this time.
I would get this error occasionally when launching a 2nd client before Apocrypha, but a reboot usually fixed it. Something with the drive perhaps?
