every time i try to log in i get "you have been disconnected from the server" when i am at server select screen and after that, when i try to log in again i get account already in use. problem started after today maintenance and 4game software update. i have tried to open a ticket to support but support is down so i had to post here. problem solved. it seems there is also a game update but i didn't get the update button in website. pressing restore game made the update and fixed the problem.
