But I did all that
I turned off Grass, Shadows, movies, enable V-Sync. Uninstalled and reinstalled the game and ran the updates again and tried all different settings again.
Then I still get a blackscreen when I go into the ebon hawk and still can't load the savegame saved at the blackscreen.
Since I heard that usually some script with a handmaiden starts when you enter the ebonhawk upon leaving the hidden jedi acedemy, my guess is I did something wrong in the previous steps?
I did start the battles with the handmaidens for example, but I didn't finish the final fight with the 5 handmaidens for example, I tried but they were too hard to beat. Maybe that corrupted things?
