How to Reactivate

[EarleH]

I have a Dell Inspiron 1012 that I upgraded my RAM to 2GiB! After the installation of the new memory, I opened Microsoft Office Word for Home and Student 2007 and am greeted by something saying "Thank You fo installing, etc, erc. I phoned in (the note book was not connected to the internet), at which time I gave that bunch of numbers requested. I was then told that it was invalid. What do I have to do to get this thing reactivated? It worked perfectly prior to the upgrade.
