In the JFBConnect -> Autotune area, at the bottom will also be details about your subscription information. It should show the user name and when the subscription is valid until. With that information, you should be able to reset your password on this site and login to verify your account that way. You'll want to have access the account you originally subscribed with to get updates, like v7.0.4 that came out earlier this week, anyways.
Thanks,
Alex
