i am having the same problem of the game crashing everytime i use any of the trainer options. either i turn them on at the main menu or during the missions, the game crashes. i am running on windows xp and i need help desperately.
i actually did the same thing by clearing the keys, but the game still crashes. i am really stuck here. i hate to say it but i mite have to wait till the megatrainer comes out. does nebody have ne other suggestions? could the mission parameters effect the trainer?
