Solved Login takes too long and then fails

it has been a long time since i played on this server and now i wanna join again.so i open the client (upgraded, and everything) and login with my old account. It takes 10 minutes or so just showing the screen with the statues and nothing else,and then "you are disconnected" error. What should i do?

 

Repair your client with ncsoft, then apply a downgrade: http://forum.gameznetwork.com/threads/gamezaion-downgrade-version-4-7-5-x-4-7-0-8.186209/unread if you have any trouble let us know it.
