So i just purchased a 30 day key and its telling me the key has already been claimed? how do i get this key onto my account?

Ok so i used a different email i guess for this key, is there away to switch this to my other email? I purchased so much other crap for my lifetime key account and i'd like to at least get to use that stuff i paid for
