When I goto play a season game, the loading screen comes up and then, I crash back to the desktop right as it is finished loading and I get an error message at the desktop that says: "Device Error". But when I go into training, it works just fine and I can play and do whatever. What is the problem

have you installed any add ons...IE:> kits or stadiums etc, this was a major prob with Fifa 99 when one of the "official" patches got released, i have experienced the same thing with Fifa 2000 after i used add ons, try the game with a clean and fresh install, that should fix the problem...
