Activating Win8 Pro afetr installing Media Center

I installed Media Center & now I can't download a key for it!

I am IRATE at MS!!

I have 2 computers running Win8 Pro. I got the key for Media Center on one computer & everything works!!

I then loaded Media Center on the other Win8 Pro computer, but it will not let me download a key for it. It insists that I have downloaded a key!

I tried to reactivate back to my original installation & refuses to accepted that valid key!

I don't know how they know I have downloaded a key.

What do I do know? Reinstall the original Win8 Pro? Ridicules!!

There must be a way!!

After using MS Software from the beginning I am getting more & more frustrated with MICROSOFT!!

I want to buy a Surface RT Tablet for my wife, but there is NO WAY I can buy one in IRELAND!!!F
That Old fart TULLY

If you are referring to the free keys, one key works with one install. I had to supply two e-mail addresses to get two keys.

I assume the purchased keys work the same.

One Media Center key = one email address.

Don't work for me!

Will try my wife's computer, but she has Win7.
