I have a Windows 8.1 which I upgraded from my purchased W-8.
Decided to order the Windows 8.1 Media Center Pack.
Ordered online, $9.99 and installed.
Got Windows Activation screen saying Windows can't activate right now. Try activating later. If that doesn't work, contact support.
The *******B7TTT Current product key is the new one I just received.
Entering my old W-8 key doesn't work.
