I was able to finally log in on one character, and did a trial. Afterwards I logged off to hop on an alt. It took me a few tries to get in, but I finally did.

After playing a few minutes on the alt, I dc'ed, and haven't been able to log in since. I can get to the character selection screen now, but every time I try, it goes to the loading screen, and then pops me back out with a 'world is currently full' queue - which is fine, of course, I'm used to those - then pops back into loading, and just a few seconds later I'm again popped out, but this time with a 90002 error, 'connection with server lost'. Then back to title screen to try again.
