stuck in quest loading

[Veridin]

I started Cannith crystal quest group hard. After the "loading please wait" bar fills up, I stay on that screen. My party member sees me in the antechamber but I'm not doing anything.
I tried to log out and bag in, when I finish the "loading please wait" bar, I'm still stuck in Korthos Hall. My party member left the quest but I'm still stuck in limbo.

How do I get out?

Actually I just tested the starter quest with a new character and same thing happens. I had no problem loading quests until the full game finished downloading...
