A while ago I downloaded a torrent of Office and that worked for a while, but now that I'm at college it doesn't allow more than one person to use the same product key on the same network. So I went out and bought Office 2004 but it still thinks the old product key is the product key. How do I completely erase everything Microsoft Office-related on my comp? All I did was drag the Office and Microsoft Update icons in Applications to trash. Thank you in advance.
