I am getting game crashes using the latest trainer. It usually occurs during a killcam with my first shot. I've verified the game cache and also ensured that the trainer was running with admin privileges.
I tried starting a new game and didn't activate the trainer till the part where you snipe the officer. The moment the bullet exited the man's body, the game froze. The crashes might be due to the killcams?
yes the fine developers of this game got tired of people using the trainers in Multiplayer and also getting super high scores in the leaderboards so they added 100's of steam scan triggers to crash the game if it determines there is a change in the game .exe.
you can message them on their forums and thank them for making these changes so that you cannot mod or use trainers for this game any more.
