I played this game for the first time today (love it!) and I was playing co-op.
We entered the teleporter on third level (after clearing the stage) and the game instantly crashed for me before the transition to the next level. We tried again and it crashed at the teleporter for the first level, same happened on the next try. I restarted pc, crashed on teleporter of third level. I disabled SLI, same problem. I tried compatibility (Im running windows 7 64 bit) set to windows XP service pack 3, same problem. Tried windowed mode, same problem. I reinstalled the game and everything seemed to go fine but I had no sound so I reinstalled the vcredist (as suggested in this forum) and I got my sound back. I decided to play solo for a bit, got to the teleporter on the forth level (after clearing the stage) and my game crashed.
EDIT: After further testing with this bug it seems that the sound may be related to it, that or its just coincidental. I will start the game with music in the background, all weapon sounds and all other sounds are fine. On the second or third level the background music will no longer be playing. The level after that the sound will have stopped completly and nothing will be heard. On this level the teleporter will cause a crash. Upon restarting the game there will be no sound what so ever which can be solved by the solution in this forum. I have done this entire sequence four times now so I'm assuming its not a coincidence.
Fix: Im embarassed to say but it was a sound issue. I have the Asus Xonar D2X Audio Center and the solution was turning GX mode off. The game runs perfectly fine now. I didnt even know GX mode was on!
