Blocked Product Key for Windows 8 Pro

So, I purchased a copy of Windows 8 Pro on Ebay just over a month ago.  I was able to install AND activate Windows 8 Pro successfully at that time (1 month ago).  It was a clean install on a brand new hard drive.

However, I decided recently (just a week ago) to upgrade a bunch of hardware (video card, monitors, power supply, and also temporarily the hard drive)... and in so doing I did a fresh reinstall of Windows 8 (first on a test harddrive, and then on the harddrive that I had installed Windows 8 on a month previous).  With both of these fresh reinstalls a week ago, I was unable to activate Windows 8.  My product code is blocked.  

Am I blocked because of my hardware changes?  Or, am I blocked because I purchased a bad Windows 8 (e.g. maybe I purchased an MSDN code)?  Here's the output from Licensingdiag.exe.

Thanks so much in advance!
