im having the same problem, no error messages no nothing,
Had the same issue with Gothic 4 but i figued it was just that game, but i bought this and installed fine, but nothing ever starts.
I installed the physx drivers that came with the game and just updated them to newest version.
My directX is fully updated and so is my 2 amd 5770 HD cards
running Windows 7 64 bit 8 GB memory amd processor quad core.
