In the last 1-3 hours my computer has gotten so many errors its going downhill into nothing. It all started with i think downloading essential windows ME Updates, or re-activating Comet Cursor. Anyways i started getting errors with WMPDXM.DLL then after that none of my folders on my windows desktop will open. i cant get to any folders in the run box or the find or control panel. Ive tried everything even system restore and it dosent respond. Im thinking of -installing the computer, but i would be loosing alot of ESSENTIAL computer information, like EXTREMELY IMPORTANT video files from a camera. I hope anyone can help me im in a state of a nervous breakdown help
