After typing the id/pass, then selecting the server and reaching the character screen. I enter the pin to log in but the screen freezes and my character doesn't log in, even after waiting a few minutes. It doesn't even get me any error like, "Cannot connect to the game, please check the network", i don't know any way to reach in contact with a GM. So maybe this would help, if they could fix it please.
P.S : I have also tried all my other accounts and it still doesn't log in.
