Sounds obvious I know, but just incase nobody knows, everyone who wants to do the DWB should have spoken to Boba Fett about it in Jabbas Palace first, otherwise you wont get in.
Oh, is THAT what he's on about? I did all his clone relics quests, and he mumbled something about someone that I didn't pay attention to, and all he'll say now is go kill whoever it is. Ahh, I see the light now
Everyone needs to do that. I remember an LxA outing to the DWB with only a couple of people actually able to go beyond the entrance without getting "bounced" out. Everyone else managed to get in far enough to drag a couple of SBD's out.
