Deleted download email and cannot get into humble library for steam key.

I was not logged in when I bought the game and bought it using a different email address (All email accounts mentioned I still have access to). I deleted the download email and thought nothing of it, but now everywhere I read I am told i need it to add it to my humble library so I can retrieve the steam key. Any help?

If you contact our support e-mail. and include your transaction ID (the one that starts with X) we should be able to get you your link.
You still may need to find the confirmation email that contains your transaction ID (if you deleted that as well... Support may still be able to help you. Another idea, is to go through your browser history to find the humble bundle link. But try support first :)
