Hello PMCM,
Thank you for posting in the Office Genuine Advantage "OGA" Forum. First under NO circumstances should someone try to download/distribute ISO images for software from a P2P file sharing site or use a second-hand burned copies of software. Research has shown that about half of the software copies available on P2P download sites are infected with root kits, spyware, Trojans, and other potentially harmful malware. One file in particular was very alarming. This file was an administrator account giving the attacker full control over both your system and data. I would be very concerned about your system integrity because Windows is non-genuine.
With this being said you may want to back up any and all data and perform a complete reinstallation of your Windows. Next install all service packs and other updates along with antivirus. Then install your newly purchased Office and validation should work fine. Please visit http://www.microsoft.com/genuine and http://www.microsoft.com/piracy/. Here you can read more information about being genuine as well as what non-genuine software can do with computers.
