my windows 8 pro key stopped working to activate my laptop after formatting the hdd but its not an upgrade key.
I had windows 8 pro installed on my laptop, then it started saying that it needed to be activated. but when I entered my product key it said it was an upgrade key and could not be used. the hdd in my laptop was failing and causing a lot problems with the laptop so I thought it may be the hdd.
I tried reinstalling but it still gives me the same message. after I bought a new hdd for my laptop it still gave me this error after it installed. but I don't know why im suddenly getting this error, I've never had any problems activating before after formatting my hdd. I don't have to put the key in with the 30 day limit, but its annoying when it nags me about it and I need this fixed.
(I always format my hdd before I install any os. the key was working fine for a few months until my hdd failed.)
