Here's the deal...

Purchased the game yesterday.  I installed the game via DVD, but after playing tutorial for 5 mins, my mouse began freezing and / or jumping.  I have also experienced the music locking up.  I uninstalled the game and reinstalled it via impulse, but I run into the same problem.  I have lowered some of the graphic options even though my card is more than capable of handling this game.  I have the 1.05 version, and I have updated my video card from nVidia.

Here are my sepcs:

Windows XP Service Pack 3

AMD Athlon 64 X2 Dual 4200 (2.21 GHZ)

3.00 GB of RAM

NVIDIA GeForce 7900 GTX

I would really appreciate some HELP!  Thanks, Razor
