I wouldn't call this problem a crash, because you can still walk around you just can't see where your going. I tested this by moving around, then proceeding to save...once that is done i went to load game, it then updates a picture of where you are on the ebon hawk.
btw i also noted that when you go to map it shows the ebon hawk as the title BUT the entire screen where there should be a diagram of the ship there is only white space. You can also pause the game, and it updates properly on the screen with the rest of the screen black.
I have tried to load the save files from the ebon hawk where there is a black screen but it wont load them at all. The loading bar goes bout i`d say 30% then just stops.
I will trace the steps to give you guys a little clearer picture of the steps i take leadin up to this "black out"
-I proceed to the ebon hawk
-I board the ebon hawk
-Cut scene with the jedi(i think her name is arteis or something o_O)
-A loading screen appears
-We are on the ebon hawk and i have a black screen
