As topic says - every time i create party the game instantly crashes, without letting me start playing. Bought and downloaded game this promo weekend, clear instal, no patches. Win7. Help pls?

Solved by patching.

Which patch did you use? I just applied the unofficial patch and I'm still crashing after creating a party. It doesn't exactly crash gracefully either.

I had the same problem with crashing after party creation, but running MM7setup.Exe and selecting Hardware Accelerated 3D helped.
