--- Comment #10 from someprogr someprogr@yahoo.com 2008-10-26 15:11:56 --- the Homedir is on ext3. I am reinstalling steam by doing rm -r ~/.wine and then winecfg followed by wine start SteamInstall.msi.
I have also checked the integrity of the files by doing both "Verify integrity of game cache" and "Defragment cache files"
