thats funny because i have sp3, played the game twice on my computer then go for the third time and it gives me this error. im trying a reinstall now. It does not have to necessarily do with your computer or service pack.

By the way, if you have .NET 3.5 AND any other .NET version, uninstall the older version and keep the 3.5. This way, you only have one version of .NET on your computer. I remember having read somewhere on http://www.bethsoft.com/bgsforums/ about this. The person figured this out (he was running vista), and said that he gained FPS and reduced crashing. While this wasn't a GTA game (of course), he mentioned that it also worked for other games. I tried it, and it seems to have worked for me, as I crash rarely now. Just a tip.
