Have not the quite same problem, but special if i play predator challenge mode it's stop working like 3 sec and goes back ingame. But 5 minutes later my game crash to desktop with a GFWL crash message.
Got the game from GFWL shop, and version in the menu says "1.0" and does the trainer only support "1.1" or does it support both version?
