I hate the people who make these threads, but, all morning I've been stuck on the, 'Logging In', part of logging into the server. I've timed out, restarted my computer, and looked online. It says it was usually a server-side error, where the server was bogged down, or offline. The server (probably) isn't offline, so that only leaves the problem with it being bogged down. I heard a restart fixed this.
Now its an internal javasoft-thing error.
the servers down you just have to wait and be patient.
I was not told.
But you should be able to put 2 and 2 together. If you can't log in it is almost always on the server side of things. Just be patient and it will fix itself.
