Crash at Loading screen

[RedOctober]

Whenever I come to the first door that loads the next area I open it, the loading screen opens and then it crashes saying that there was an access violation.

I have tried re-installing it, turning the graphics to low, turning SSAO off, turn off all post processes, ( those last two actually made it crash faster) running as administrator (or running steam as administrator) giving it full access, (although no custom accesses because I wouldn't know what to put,) and checking the file integrity on steam. Nothing has worked and the money I have spent on it and the plans I made with friends to play it have been wasted.

I also pre-ordered the game through steam.

Any ideas?
