Or as I said, you can update in manually.
It's easier manually as on the nvidia site you have to put it the types of it and other information, if you are not good with graphic cards & sound card, I'd recommend to do it manually.
Or just try to re-install it.
I'm sure nextgen will be able to help you as he is smart with Computers & Technology.
But I'm thinking of what could be the cause of the problem.
Have you played it before? on the same computer or what?
