I am able to start the game but it only goes to the end of the Los alamos cutscene at the very begining and then a windows error box pops up saying the game has crashed and windows is looking for a fix. I have tried a bunch of different forums but seem to be ignored on them so am hoping for some help here. I am running win7 home premium with quad core running at 3gig, 8 gig ram and a GTX560TI video card. I have DEP off and all drivers are up to date along with win updated, also DX current.
