Ive done all the planets and am trying to go back to dxun to answer the "urgent message" from Kelborn. Everytime I try to zone into the Mandalorian camp the game has an illegal operation while loading it. It never did this before when I went there. Any ideas?

You should be automatically be taken straight to the camp if memory serves. If not try talking to the guard standing next to the Hawk and get him to take you there.
