Transformers: Fall of Cybertron - Damaged Saved Game Error (No Ending)

Partner Your channel /w Maker Studios/RPM: http://awe.sm/jKzY9 I have no idea what happened here. I was playing it and it was fine and the next day it wouldn't start. I am sorry but I can't afford playing it all over again 'cause I have school and need to study. I am really sorry. Hope I will make it up for you.
