Hi, I seem to have the same issue. The game systematically exits after some time when playing the mod, independently from the number of players. The graphics are on average or low because I had the "running out of memory" error a few times, but that was resolved by lowering settings. I was able to play several times complete games until this started occurring. I do not have the cd, neither for bfme2 nor for rotwk, if that's what you meant by a crack. I do not use SweetFX, at least to my knowledge. Since I first had the error, it has occurred on every game, not erratically.
