But i can't speak to Kreia, and when i go to the prison room Boa-Dur is laying on the floor, and isn't awake or anything! So it seems my game has glitched up. Is there a way to resolve this without restarting the whole game?

Does anybody have a Save game of this where everything is normal? or of the next area? please help me I'm enjoying this game so much for it to just be ruined
