--- Comment #111 from Nicky nheart@gmail.com 2011-05-11 10:29:30 CDT --- Is it just me, or the people using the DVD version with wine are not having this problem? Also the bug fix reported by valve was "Fixed installation issues when using FAT 32"
Could it be that the problem is the actual download and install of the game? Could anyone confirm this? If you've purchased the game online, could you still use the DVD to install?
