Larian Studios Forums Divinity 2 - Ego Draconis (English) Technical problems First Aid : when Div2 does not start or crashes

I downloaded the demo before buying and couldn't get it to start. Upon loading the game, it showed the 1st 3 loading screens ("Larian", something else, then the 3rd credit screen). After this screen it crashed. I thought it was a demo problem, and bought the game anyway. Same problem: game will not load past the 3rd credit screen. I've reinstalled several times, with and without antivirus SW.

I've tried installing physx, directx, and updated my nvidia driver. I doubt this has anything to do with securerom as the same thing happened on the demo version. Can anyone provide help here, in english? I'm not a computer wiz and pretty much at the end of what I know how to do. I really want to play this game but just about ready to give up. My system is fairly robust, and I haven't had any trouble playing dragon age and anything else (RPG or FPS) that has come out in the last year. thanks.
