Splinter Cell Pandora Tomorrow Game Problem

During the Komoto Shipyard mission, every time I grab the control room technician, interrogate him and then force him to raise the submarine using the computer, there is no call from a technician on the sub to inform the control room technician the sub has risen. The automatic video sequence that starts when the control room technician plays with the computer stops after the sub rises and no call comes in from the sub technician. If I try to interrogate the control room technician further, nothing happens. If I knock out the control room technician, the game ends automatically. I have run this mission 20 times from the start with the same result. Is this a software glitch or am I missing something?
