Battlefield: Bad Company 2 Discussion
You probably died, and the trainer you are using is keeping you from triggering the "restart-from-last-checkpoint" event.
To fix this, don't get too close to explosions. With the trainer enemy bullets should not kill you.
Explosions will still cause you to die and thus the black and white colours.
( I would also advise not using the pirated version as it has bugs that the legal copy does not. )
