my friend had this before, he was used to use E-mail login until one day he accidentally clicked the Facebook login and suddenly his account was deleted.

And I'm sorry to say this, but my friend had sent an E-mail to DMM regarding this accident.... to no avail, even after getting help from all of our other friends who knew Japanese to create a Japanese letter to DMM. He decided to get a new account.

hopefully you're just using a wrong e-mail though.
