Same thing happened to me. I created a ticket, then they responded saying that my account was hacked! But a friend of mine had the same exactly problem, and they told that it had something to do with Dinamic Ip's or something like that. The thing is, i was playing on the EnMasse servers on the same day that the NA servers went up! How my account was hacked simply by going into other server?
Edit: Se tu entrar no grupo do TERA no Facebook vai ver algumas pessoas com o mesmo problema
