it's just as I posted in title, 
I get the id signature for ebon hawk, then choose 2 companions which will board the goto yacht, then 2 cutscenes appears and then nothing. blackscreen/crash to windows. 
I also noticed that in autosave (the one that creates for entering goto ship) I have still the same three companions not the two I have chosen. 
anyone has any idea? this game is so buggy, but I was able to fix little bugs by myself, 
but this... this is to much. could someone please hel me?
