I forgot to add an e-mail and lost my password. I remember the username and the server # tag.

I lost the password for my account "GroszekGuardos". I didn't enter an e-mail. I can run a server using diffrent account (acc that is allowed to do this), I have a server # tag.

Is there any chance to restore my password, or add an e-mail to that account? If not, I will be thankfull for sending me world file from that tag.
