deleted. Help!? I recently have downloaded some videos with the Xvid codec and every time I go into the folder Windows shuts down. I read the FAQ at this site (http://www.xvidmovies.com/faq/#3.4) and I tried deleting the xvid.ax file located in my Windows\system32 folder and it keeps saying 'Access Denied'. Is there another way I can uninstall the Xvid codec and then reinstall the latest version? I tried going into my Control Panel and searching for it through the Add or Remove Programs area, and it wasn't listed. Please help.
