Myth Drannor problem on Naga map

[NoBZ]

I apologize if this post has been done already, but I had no idea how to search for it....so, here goes......

I am in Myth Drannor, North of the wizards place. There is a naga there that asks for help beating down on the orcs and destroying their idol. Easy, done already. My problem is in the NW corner of this map. There is a signpost you click on that says Gargoyles have marred the surface and made it unreadable (or something to that effect). The drawbridge then lowers anyway and allows you passage to the lower area north of this spot. No problem, done that too with no hitches. While in this map I entered the doorway all the way east and it brought me to the beginning of the dungeon you start out in. Upon exiting the dungeon to get back to this point it exited me into the beginning map where Nottle and the tree elves are. I made my way back to the Naga map in Myth Drannor and can no longer take the drawbridge/stairway down to that next area to the north. My icon doesn't change to the new area icon....it goes from the walking icon to the red X. Anyone have similar experiences, a fix/solution to this problem, or a work-around? I'd be greatful. Thanks a lot!
