I am playing Black Ops on a PC. The game has worked fine to this point. But when I jump the gap in the bridge and run from the avalanche, most times I am right behind the other team members. But when I get to the cliff I have tried jumping and running straight. The screen says "You did not keep up with your team members" but in the upper part of the screen I get a message that says Objective Completed. What am I doing wrong? I have tried this section probably 200 times! Thanks.
