I've Lost my key...

[Bobo]

Hello. I bought this game quite a while ago (I want to say during beta 4), but I've since updated my email accounts from charter email to gmail. I had the info on a note file on my old pc, but that hard drive is now corrupted, and I didn't have the foresight to write out a physical note. Now I have no access to my old email accounts, so I don't know how I can verify my purchase. I do have the same pay-pal account linked to my new email if that is of any help. If there is any possible solution, please let me know. Thank you!
