Kinda old post but i think an answer to this issue will help some players get through it
Well i had the exact same problem like 2-3 hours ago, i've tried searching over the internet for an answer and i came up with nothing but posts like "I reinstalled my OS and the game and it crashed again."
I spotted a glitch where you can control your char for less than 1 sec if you left click every cut scene ( Mira's one mostly ).
So what i did was :
1 : Saved the game ( NOT QUICK-SAVED )
2 : Opened the door.
3 : Spammed left click + 1 so i go fast to the next cut scene with Mira ( For light side guys for the dark ones dont choose the "Leave him alone" choice before they kill Visquis ).
4 : When Mira's cut-scene appeared i spammed left click and managed to have my left hand on "W" and "F4" so i can move 1 step and quick save really fast after the cut-scene. ( Dont really know if the step move made any difference to it. )
5 : I managed to make 1 step and quick save during the glitch between Mira's CS and Keira's CS
After that i watched the next CS and it crashed again.I launched the game, loaded my quicksave and ... IT WORKED. It loaded just fine!! NO Keira CS and i could move and do ****.I got my light side points aswell moved around the room a bit, quick saved again and quited the game as i am going to sleep soon.
Well i hope i can continue the game (since there was no Keira cut scene coz i saved just before it comes) and Good luck to all of you guys having that ****Y problem. I guess it's the only solution available on the net besides the "I'll give you my save, please get past the crash" one.
Give it a try let me know if it works for you.
