I've had Office 2003 Pro installed on my machine for several months now.
Recently I did a registry clean and now wordf and excel are asking to do a
product activation again. For some reason word activated fine, but excel did
not. I'm not paying $35 just to get microsoft to fix something that
shouldn't have happend.

Any ideas on a free way that I can get my product activated by microsoft?

I bought office through a Microsoft-Campus agreement at my school.

thanks
