You can recover your CD or login here: http://dof.reverieworld.com/passwordrecovery.php
That system will email your info to the email registered with your Online Kingdom Account.
If you are unable to recover your login using this system - please let us know any info you can about your account and we`ll try to look it up for you.
If you might recall your username, or know your CD key, or at least email you might have used when registering your account we can help.
Keep in mind - that if we are unable to locate your account, all we can do is offer you a new free CD key so that you can create a new account, but all your progress on other towns will be lost.
