[H] windows 8 with media center

[Winterlight]

I own a Homerun Prime cable tuner that I use with Media Center. It 
has been my  my TIVO for the last six years, and it works great.  I 
am in need of a Windows 8 Pro with Media Center key. I would purchase 
one but that are unavailable any more. I am hoping someone has one 
that they  never used or used, and deactivated, and would sell it to 
me. I know windows 7 supports media center, and I am using a 7 Pro 
PC, but support for 7 ends in 20 months while 8 is good for another 5 
years. Somebody with an available key is a long shot but I had to ask. Thanks
