I am using a GeForce2 Ti and have just installed Return to Castle Wolfenstein which will play for about 5 minutes before I get the "WolfMP.exe has generated errors and will be closed by windows". This happens everytime even in single player, as well as in Multiplayer. I have changed Graphics drivers numerous times so I am assuming they aren't the problem. When I installled rtcw i also installed directx 9 - could this cause the problem ?
