I had a Trial version of Office 2007 on my home laptop which I purchased last
year. It prompted me for product key after a few uses. I bought Office 2007
Professional (from the Microsoft company store - I work at Microsoft). I
typed in the product key from the CD and activated, and everything worked
fine for a few months.

About 2 weeks ago, Office apps stopped being fully functional on my laptop.
Instead it shows "reduced functionality" - i.e., I can view a word document
but none of the editing functionality works. Now from the Word options dialog
it appears like the software is not activated. However, clicking "Activate"
from the dialog does not start activation wizard.

I uninstalled the product, and reinstalled from the CD. No difference
whatsoever. The product still has reduced functionality. So now I'm stuck
with a retail product that I cannot use. Some searching on the internet
reveals that the Trial version of Office seems to be a nasty bit of work -
there are numerous posts referencing the inability to use a retail version
once you install a trial version.

Is there any user, Office dev team member or MVP that knows the correct way
to resolve this problem?

thanks
