Install Windows 10

My computer is currently running Windows 8.1 Pro for two years and the key was authenticated when I installed Windows 8 Pro (and subsequently upgraded to Win 8.1).

I downloaded the Win 10 Pro ISO and burned it to a DVD for installing purposes. I used this DVD and did a clean install of Win 10 Pro. When I entered the 25-digit Activation Code (from my original Win 8) I received an error message stating that the Code
I entered is blocked.

How do we (myself and Microsoft) resolve this issue? (My computer has Win 10 Pro now; cannot be activated because of the Code blocking).

Thank you in advance for your replies!
