Windows 7: cannot use product key to reinstall Office 2010

cannot use product key to reinstall Office 2010

I was having lockup problems with Excel, so I uninstalled 2010 upgrade and Office 2010, and when i tried to reinstall it, MS gave me a message saying the product key was invalid. I bought the 2010 upgrade and I have the correct product key from that installation. I verified that I entered the key correctly (it was correct). I am now toast.
What do I do next??
Thanks in advance !!!

I'm wondering if you're going to have to input the original Office key, then the upgrade key. Please let us know what you successfully did so we can learn from your experience.

Also when you contact Microsoft by phone you will need to have both your old disc & the upgrade disc available as they will ask you for details of the activation codes.
