Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello I am new here, been playing on peenix earlier but I want to move over here but there is just one problem... I can not create an account, I fill in the blank spaces, do the capacha (click the right pictures) everything checks off fine but when I click to submit, page just reloads, listed passwords are removed but the rest of the information is still there but no account created. Can anyone help me?

Thanks in forehand
