Change account bug

I wanna change my real account from facebook log in with a normal account (blue byte)
And first time I logged on test server to see if works
After close the aplication of settlers online test server from facebook I got mail if I want to trasfer my account.
I added pw, date, nickname with big,small letters and numbers and still said its not valid to create account.
"The login attempt failed. Please check that you have entered your player name correctly. Please use the correct upper and lower case characters in your password."( that said )
And I've tried 20 times and nothing,
After I logged with facebook again and I losted the old account from test server, and now I have other one with other nickname
Sorry for my bad english.

mail support please.
