The tower in the Broken Valley village? There are different entrances there you can try, one off the wall by the main gate, one from the wall on the opposite side (which is almost a ramp down to the door), one across the bridge from the merchant Lamotte (also up the ramp from the main gate side wall), and one up a ramp on the right if you keep going straight from the entrance gate.
If entering an getting a cutscene conversation is a problem, the another entrance may be fine.
If the problem is the location itself, perhaps a clean re-install may help.
