Hi all!!! I have a game with all the jedis found with the light side and i must return dantooine, i talk with kreia and say me that she has to talk with me, then i go to leave the ebony hawk, i select my party and then appears a full black window with the game pointer and not appears the loading window. I've reinstalled the game and tried the savegame in other computers. What can I do? Thank you!!!
