Hi, upon purchase of Counter-strike: CSS, I was able to play for a month at most, steam updated and I was no longer able to load the game, an hl2.exe error comes up after "preparing to launch counter-strike source" comes up. Error signature: AppName: hl2.exe AppVer: 0.0.0.0 ModName: shaderapidx9.dll ModVer: 0.0.0.0 Offset: 0002e02a. I use an Ati Radeon 9200 Video card with a 2.0 ghz computer and 512 mb of ram. I have updated direct x, and my display driver, althought STEAM says I hasn't. I have a newer version then what steam reccomands.I can play 1.6 Just fine, never crashes.Any Help?
