Hello everyone,

I just updated my Windows 8 to 8.1 through the windows store, but now I can't activate it, using my product key. I got my Windows 8 through Dreamspark and then upgraded it to Media Center edition.
Both my media center key and the key I used to initially install 8 don't work.

Any ideas how I can fix this?
