I am playing KOTOR 2 on xbox for the first time, i complted oderon first, then went to nar shadda, i've completed the refuge sector and done all the quests i can, the bounty hunters appeared, mira and the wookie but when i walk up to them and use dialog, they just turn to face me, nothing happesns. also when i talk to the twilek Twin sun, it goes to a scene where i walk into the entertainment area and the two twileks talk, wait, ect. I tried paying the 2000 credits but that doesn't do anything either.

Can i do anything other than start again?

Reading through some other people's threads, i thought i should add this;
I am running an plain old xbox in standard conditions, no extra mod's or otherwise in this case. I think it could jut be a bug that everyone seems to come across eventually, but it bites a bit after completly finishing telos and duxon/oderon ie 32hours, and since this is the first time i've come acroos it, i don't save as often, my oldest save is after the bug occured. Does anyon know how to reset triggers or something that might fix this? Thanks

did you go back to the ebon hawk and fight off all the trandoshians?

No, i've given up and am restarting, after a long break due to frustration.
