Claire1982,
Right now, your computer has a Volume Licensing edition of XP Pro installed (Line 8), and that installation was done with a now-blocked Volume Licensing Key (VLK) (Line 2). VLKs are blocked by Microsoft at the request of the original keyholder for such reasons as the key was lost, stolen, compromised, misused, or expired. Also, MS may have blocked the key if it notices a pattern of misuse, ie, more installations of XP using that key than authorized.
If you search the forum for the part of the VLK reported by the mgadiag utility, PD6B3-FDJ4G-RGV8B, you will see that four other posters have submitted reports with that same blocked VLK.
As a rule, VL editions of XP should not be sold to individual consumers. Businesses, schools and gov'ts normally use VL editions for flexibility in installing many computers. Also, Volume Licenses are Upgrade Licenses only and cannot be sued as original or base licenses on a new computer.
This is why you were seeing the "software counterfeiting" messages on your computer, because the current installation of XP is an unauthorized installation.
Look on the computer, or in the materials that came with your computer, or with your retail purchase of Windows, to see if you have a Certificate of Authenticity (COA). If you have one, tell us about the COA. Tell us:
1. What edition of Windows XP is it for, Home, Pro, or Media Center?
2. Does it read "OEM Software" or "OEM Product" in black lettering?
3. Or, does it have the computer manufacturer's name in black lettering?
4. DO NOT post the Product Key.
