anyone have any luck with this?? Please someone....

Here is the link that I used initially to get into the game. I've tried adjusting the settings, but eventually gave up. If u figure out how to get it past the intro without crashing, let me know. Thanks, hope it works out for u.

I just downloaded assassin's creed and i tried running it with the 3d analyze setup of GH3. the game starts, i see the intro, then it crashes out to the desktop. I'm trying to fiddle with the 3d analyze settings, but i'm not sure where to start. Can anyone help me out? thanks...
