I can not create EA account

Hi. I had account whit my e mail adress linked whit ea and then I changed that email adress whit new one, also I changed that linked email whit new one so right now my old e mail adress is not linked whit any account or anything.

After that I tried to create the new account whit other region but I can not create account at all, it says wrong e mail or pasword. Why? I think if I removed my old email I should be able to create new account whit that e mail.
