I'm in the dormitories and killed all enemies up to the Shift Assignment Console and tried logging into the computer but it won't respond. I was thinking maybe I just can't access it right now and come back later until I got to the Turbolift Access Console and I can't access it either. I cannot return to the Airlock to Asteroid Exterior because it is locked so I am stuck. I've tried reloading my save and even created a new character from the beginning since it isn't too far into the game and the same thing happened again! I cannot get past this point in my game.. I'm wondering if it has to do with the few minor scratches on my disk because sometimes when I'm loading into a new area a message comes up and say's im using a damaged disk. I want a new game because this one is used but the only one I can find is almost $90 on amazon...Anywayz any help on how to get out of the dormitories would be great!
