EQ just drops to login after picking server

[Lucia Moonglow]

I've tried every possible iteration of this, including running various launchers both as admin and without, with and without compatibility mode...

I got it to work once, but couldn't play at the time.

What happens is when I log in, I put in my username and password, click connect, and it takes me to a server selection. I pick p99, click login, it waits for a second, then drops me back to the username/password login screen without any errors.

This is a default Titanium installation modified only by Duxa's all-in-one tool and patched by the EQEmu patcher (which currently can't detect any servers).

I'm at my wit's end trying to figure this out.
