so, I've installed AC on my laptop, and the intro trailer runs fine but as soon as it stops I get a pop up saying there's been an error and the game has stopped. Is there something I've done wrong or...? Ghz is 1.7 I think, but it's duo, so technically it should work... right? Any comments?

Post your DXdiag so we can get a better idea of why the issue is occuring. It might be because laptop graphics cards aren't supported by Ubi.
