The fact is, if you're on Naia and you're logging in from outside the US (not sure if this affects people in the US) you'll probably never be able to login until the next maintenance/server is rebooted or you can try when a big event like Oly/Dim Siege is on. This has become apparent for the past 2 weeks or so. The login server is fine (try keying in a wrong password, if do manage to get the login dialog that is, and you will get the incorrect password message in seconds. The server is so packed now (that number in party matching has been growing, it's usually ok to login if the number is 3500-ish and below, but now its consistently 4200+ most of the time) that even if you do get past the login dialog you will never be connected to the game servers. That's what's timing out and the error message code you get is always 0 or -1, error message is always "Try logging in later". You can keep trying though and hope to get lucky. I manage to get 1 client running after dozens of attempts. Far cry from 6 clients last week all connected for more than 100 hours. Oh yah, even if you do all these things and connect successfully, you have to wait in the queue. Good luck with that.
I've ditched the game now, it's no use wasting time on this until the next maintenance/reboot. The issue seems to be the transition between after logging in and connecting to the game server (and the fact that the Launcher cant to show the login dialog too). Then you'd better login and STAY in for the rest of the week as I've been doing this past month. It's a joke really but who cares..
