If you don't know what it is than you don't use it. Here is a link if you want too read up on it. Anyways, back to your problem. I am not sure why it won't work since it plays the rest of the game perfectly (?) so it is probably not a graphics problem. Give the blog some time as I am sure there are plenty of other PC gamers on here who will be able to help you resolve this.
