The email I used is no longer in existance, I think it was netscape, which closed down. Bravenet doesn't recognise my existing email adress so I can't log in or find out my username or passwords.

BRAVENET ONLY recognizes the E-mail address you signed up with when you got an account

SO IT WILL NOT recognize one if your one you HAD with your account is no longer active

What you SHOULD HAVE DONE was gone in before that email went to change to a new one then you could have gotten in then.

NOw you have to open a ticket someway to contact bravenet to get your login information to change your e-mail address in your bravenet account.
