cloudiewaffles I've merged your post with another thread about the same issue. Please try the suggestions earlier in the thread.
I'd also like to see a dxdiag, in case there's any relevant similarity between your system and the other player's. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
chugpug30 If the clean uninstall/reinstall doesn't help, please post a dxdiag as well.
