Yeah post the specs on your video and sound cards. Also try running dxdiag to verify everythings ok with no errors. Also were you able to go to Edit Players before? Did this problem start after trying to patch something or after installing a patch?
More than likely its going to be the shoe patch that you installed. You have a decent PC so your specs are ok. If it is a 2x shoe patch be sure that you have DANET's patch installed. I would roll back to the original shoe file from the CD and then be sure you can go to edit players and then think about doing one shoe at a time to find the problem shoe or do a few at a time.
