I have no idea what the problem is.
But I can say that I am experiencing this same sort of problem, but have been experiencing since Monday [4-7-2008] night. Been in contact with SOE Tech support and everything they've suggested hasn't worked so far.
The only difference for me though is that I think I seem be losing the connection at the same time I connect to the Login Server, so I get stuck at "Trying login server #1" and sometimes "Loading to zone server."
I've seen a couple other posts of people getting stuck trying to log into game as well, but able to log in through another computer. Unfortunately, I only have one.
