Forum:Locked out of Crimson Armory

I defeated Knoxx, got to the control panal in the armory, completed both tasks from the mission Armory Assult, but did not submit the mission; the timer never started. However I forgot to try to exploit the glitch before the door behind me shut, so I restart the game and drive back to the Armory. However once I pass through the yellow-blue-cyan-orange coded door, I cannot go any further. Suggestions?
