Win 8 re-install refuses activation key ??

Hi...
After Win 10 uprade, ssd decides to crash... I re-install win 8 onto an hdd using the install key and it is running perfect
until I get a prompt to activate, which I do, using the key... which Windows rejects... any clues guys ??? strangely, it also
gives me an option to stop the activation nagging .

Yes try the phone option to activate you have to many activations on that Product Key, Phone activation should work as long an there are no other actual copies activate.
