Hi Tomoko,
I just checked in the db and in fact you e-mail address is registered with your account.
When installing Mazebert on another phone you can make use of the forgot savecode feature. Or, maybe you still have the initial mail that was sent to your email address?
Anyhow, I added your save code to your forum profile as well, so you can retrieve it from there, too ;-)
Cheers
Andy
