From the S@H Website FAQ:
I'm trying to access my account, but I've lost my password. The e-mail address I used when registering is invalid. Is there any way for you to give me access to my account?
In order to protect your account from modification by others, we require both your e-mail address and password for access. If you lose this information, we unfortunately cannot help you access your account or your credits. You will need to create a new account with a valid e-mail address to access any future credit.
I am not sure if anyone else has any ideas. Who was your old email account with?
