Plot Problem Possible Spoilers

[Knickalen]

I hope this goes here, well I have played the game to completion before without problem. But for some reason this time scripts are failing to fire that advance the plot. When I go to retrieve the droid on Telos station nothing happens. We never get attacked by thugs. The ithorian says please protect the droid, the droid introduces itself, and the guard just says hello sir, and thats it. The scene in front of the cantina with the mercs never fires either no matter how many times I have passed through the area...any ideas?
