Or am I just uninformed, or otherwise, naive?

I am trying to use the XP disk (Pro) to fix problems I've been having. I chose upgrade, then put my numbers in.

Ummm, it says the numbers are invalid. They are the numbers I have!!!!!!!

Whats going on? They are MY numbers.........how the heck did they become invalid? What am I going to do to fix this thing if the numbers won't work? And why won't they work when they worked about 6 months ago.

Can someone make sense of this? Is there something I'm missing?
