Having problem with the graphics in a game

Hello. I am having issues with the graphics in the game SWTOR. I've looked on their forums and it seems whenever they have this problem its with their graphic drivers. So I was hoping one of you guys could help me sort this out.

Here is an image of the problem. The UI is fine, its just the character thats enlarged.

Here are my device stats from dxdiag:

Im running XP btw.

Thanks!
