Okay, I was on my way to do the golden claw side quest, I walked up the mountain, killed the bandits around the first tower you see, went all the way to break falls barrow and this quest marker said I have to go into the cave, but the path seemed to be cut off (I saw the underground !), I was stuck as I walked down and couldn't walk up. The game message continuously said "You cannot go that way" and yes, I had to reload my last saved game.

Tried recreating new game couple times, still the same thing happened.

any help would be appreciate.

Thanks.

I'm having a similar problem, when I go past the first tower, and up to the stone structure where the archer attacks, I can see the entrance to the dungeon sort of floating in the air. In the area surrounding it the graphics are messed up. If I try to walk toward the entrance, I get the "You cannot go that way" message and I'm stuck and have to reload a saved game.

I've found other areas with very glitchy graphics that will lock up your game as well.
