Your account is an old account. Initially (yeas ago), people logged in with a username/password combination instead of an e-mail/password combination. Please contact [email protected] with the e-mail address you originally used to sign-up as well as the username you used.
The e-mail is not being sent. This is unlikely, but we will be able to see if this is the case and why it is being rejected. Please contact [email protected] with the e-mail address of the account you are trying to reset.
