I built a new htpc. Installed win8 pro ( worst decision I ever made) and signed up for the free wmc key.
After a week I got my key and add feature, I have a key, pasted it in and it says the key won't work.
2 different people said they got 3 or 4 keys and they had no problem. So they each gave me a key.
I signed up for the key on this new full win8 pro install, this is not an upgrade.
Why will it not take the key but instead says the keys are invalid.
Any ideas on how to get this to work?
only recommendation so far is to go to the menu where it says reinstall and go from there.
