It still doesn't work...
I downloaded this patch, extracted it to the game folder, and now Windows immediately displays "The program has stopped working. A problem caused the program to stop working" after launching, and that's it (((
I figured it out: I downloaded the patch for DirectX 10 - Windows no longer complains, but the game still doesn't launch, just like before installing the patch :( That's a bummer.
I had the same problem; the game only started after I turned off the antivirus.
