Hi, If you did register before January 27th, changed your password for the new client. It will not be changed for the New Client. You have to use your previous password that were used before you've changed it. However, If your account was registered after January 27th, you will not be able to play the 2.0 at all, but you can only play the 1.0, current one as of right now. 2.0 is in testing phrase, fixing bugs before the release.

thank you! but there's a reason why i changed my password (i dont remember the old one)... is this mean that i can't play with the new client even if i have an old account?
'edit:
so i found my old password and it still doesn't work..... my account was registered at 2016.06.24
