I am trying to activate my Windows Vista Home Premium, When I put in the CD Key I get a response that reads, "The product key appears to be a default key and cannot be use for activation. I do not understand why I am getting this message! I got the activation key off the back of my computer, maybe you can help me??

Thank you
