Hey I get an error when trying to activate Windows 7 Enterprise, it says a problem occured when Windows tried to activate. I have a legal copy and a legal product key, but it gives me the error and won't let me enter the product key or go online to activate my copy of Windows 7. What do I do?

Do you have an upgrade version of 7 ? Did you do a clean install ?

I did a clean install, and I finally figured out my problem by doing some things that it said to do on this site here http://support.microsoft.com/kb/929826/
