Basically, it crashes at launch, and it gives an EXCEPTION_ACCESS_VIOLATION at Penumbra.exe and some numbers after it.
My GPU is GeForce 9800GS, on a Windows 7 SP1 x64 system. Everything is up to date (video drivers are 275.33).
Dunno what to do, it worked just fine several months ago.
Here's the log from Black Plague (as an example):
