What is your operating system (Win 98SE, ME, XP, or?). Have you considered uninstalling WMP through Control Panel > Add/Remove, then going to Windows update and installing the newest version?
At this point, this is just a thought. You may have other issues here that a more advanced member may pick up on, but if it were my system, that is probably what I would do. You might want to wait for more replies before actually doing this, since I'm not all that sure I'm on the right track here
