Okay I ordered a Certificate of Authenticity from SuperSupplier.com for Win XP pro, but when I try to use it on my xp pro cd it does not take the key as valid. I'm not sure of what version it is. Is there more than one version of xp pro, besides the upgrade? I think my disc maybe the upgrade disc and my key is for new installation. Is there anyway to get a replacement cd from Microsoft, or should I return the key and get the full OEM version?
