Just to give you some hope, I had the same problem. I e-mailed badgehelp to get my password again, and never got a response. I figured out the problem was that I was sending the e-mail from an AOL account.
Just sign up for an account with another service (Y!, Hotmail, etc) if you don't already have one, then e-mail badgeherlp from that acct. Send your reg code, some kind of proof of payment (Like Bob said), and make sure you mention the e-mail address the codes were originally registered to.
If this doesn't help, I don't know what else to tell you.
