Ok i just got win2k so don't go off on me for asking a stupid question or anything But here goes. With counter-strike, ati radeon users have to install a patch to prevent overflow error with the new version of counter. Well that worked fine with 98 se. I just formated and put in 2k. After i install the patch upgrade, when i click on counter, it gives me this error message. Your Half-Life \executable has been modified. Please check your system for viruses and then re-install counterstrike. Whats up with this? Thanks
