Windows 7: Star Wars Battlefront 2 Problem

I just reinstalled Battlefront 2, the menu in game is at a low frame rate for some reason. And the maps do not load. Before I installed Windows 7 (was using Vista), I had a similar loading problem, it would take roughly a minute for a map to load, but now they don't load at all.

Operating System: Windows 7 Home Premium 32-bit (6.1, Build 7600)
Processor: Intel Core 2 Quad CPU Q9550 @ 2.83GHz ~ 2.8GHz
Video Card: Nvidia GeForce GTX 285
Memory: 4096MB RAM
DirectX Version: DirectX 11

This game ran perfectly on Windows XP, and near perfect on Vista. I'm at a loss as to what is happening. Windows 7 has not lived up to it's promises over Vista yet, I have had many problems, shame Microsoft, shame...
