Unable to get back into Amnoon after DC

I went through the initial prologue area, got my mount, and got into Amnoon. I was just starting to wander around when I was DCd. When I logged back in, the game had me in LA though my progress in the story had been saved. However, I can't get back to Amnoon. The map there shows no waypoint even though I had it when I was there. And I can't get there via the airship any longer. I'm basically stuck. Is there any other method of getting there? This seems like a glaring issue.
