HELP ME!!!!

PLEASE PLEASE PLEASE I NEED YOUR HELP (may contain spoilers?)

I'm on the quest among the stars and I just destroyed the last generator in the cyro storage. The teleporter behind it is up and running but when it gives me the option to open it and head back to the cyro labs to speak with sally and i press the button to let me it will not go. I also tried going all the way back through everything into the labs without the teleporter but when i get to the two doors where the wastelanders are being disected in the labs it says it requires a key. Please anyones advice will help greatly. This for the xbox 360 btw
