Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello, im trying to get my account from Nostalrius to Elysium but never seems to work saying this:

"We are encountering technical difficulties regarding the token generation procedure. Please try again later."

I tryed for several hours, I know the email, pass and username, dunno what to do more.

Tks

Still saying the same, theres nothing I can do or...?

Everyone is encountering the same.
