Dxun Cutscene Lockup

[Eleutheria]

After I finish Iziz and go back to Dxun, Mandalore says he wants to join the party. Then Atton walks up... and the cutscene freezes.

 

My cursor appears, I can move it around, but nothing happens and everybody just stares at each other.

 

Since I have a save just before that part, I've been able to try things like fiddle with sound, changing resolutions, etc, but nothing works.

 

This is very frustrating, since I paid close to $50 (a princely sum for a student), and spent 10 hours getting a lightsaber...
