Anonymous,
Right now, your eMachines 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, JMMDK-X8T8M-77YVM, you will see that about half a dozen others poster 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, VL editions of XP are Upgrade Licenses only and cannot be preoperly used as the original or base license 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.
Luckily, the solution to your XP problem is simple but a little laborious. Use the recovery solution supplied by eMachines to replace the nongenuine installation of XP Pro with the genuine original installation of Windows which was on your computer when you purchased it new. The Certificate of Authenticity that should be affixed to the computer case will tell you which edition and/or version of Windows came preinstalled on your computer. Be sure to back up and offload your data before you do this because typically the recovery process destroys all data on the hard disk.
If you do not have the Recovery CD supplied by eMachines, you can order Recovery CDs for many eMachines models directly from eMachines (in the USA they charge about $25 USD; not sure what the price is in GB where you are). If they cannot help you, try http://www.restoredisks.com or a Google search of sites that sell recovery discs.
