I just wanted to add that this is an issue I've been having off and on for about a week as well.
My server of choice is Virtue.
I'll boot up the launcher, attempt to login and am met with a series of (varying) errors: Can't connect to DB server, No mapserver connection, Cannot reach the login server....and it repeats them until (if I'm lucky) it allows me to reach the point where I can select my server.
And then freezes, starting the cycle all over again.
If I'm really lucky, it gets to the character select screen before it boots me back to the beginning with something like 'please enter the password' or 'no mapserver connection'.
Needless to say, after going through this for going on four hours, I'm pretty frustrated. It's kind of bad when you WANT to play a game you're paying for but can't because of some error.
