If you forget your admin password you can recover it by issuing the following SQL commands via phpmyadmin or any other MySQL interface or console.
Also if your host updates the MySQL version your admin password could stop working because MySQL password encryption method changes from one MySQL version to another.
UPDATE cjoverkill_network_settings SET login='admin', passwd=PASSWORD('admin')
After running the SQL command on the CjOverkill database you will be able to login into the CjOverkill admin interface using login = admin and password = admin.
WARNING: Remember to change the admin login and password unsing the "Change Pass" option from the admin interface after you have entered the admin panel.
