Free trial Microsoft Office 2007 verif key they sent is not valid

[tdarcman]

I signed up for a 60 day free trial of Microsoft Office 2007. They sent me a
25 digit verification key to use, and it is invalid when I try to edit some
word documents that I already have. The documents come up as Read Only

Are you able to open a new document and save it?

Have you activated the trial?
