Xbox 360 version ?

[Mad Dawg 173]

I was playing Battle of Stalingrad "Hornets Nest" mission and at the very beginning of the level i was diving to shoot out one of the spotlights and got a pop-up window indicating some kind of error and the game went back to the Hornets Nests start menu ? i then started the mission again and completed it and no pboblems before this incident or since. Anyone else have a similar occurance in the game.....just curious ?

Thanx !
