I'm really hoping someone can help me, I've read other threads, FAQs etc, but I can't find a solution to my problem. I bought a product key for Windows 8.1 Pro OEM in Kinguin. I formatted my hard drive, installed Windows 8, it asked for my key during installation and accepted it, but once it installed I can't get it to validate, it says "This key didn't work, please check it and try again, or try a different key".
At the time it gave me the option to contact customer support, I chose to do so by chat. The representative told me I'm supposed to go back to my previous version of Windows, but I don't have a previous version of Windows that's legitimate.
Now when I try to re-enter the key it just gives me the error message but no option to contact by phone, chat, nothing. I'm stuck, please help me.
