GeeGee,
Only the general's eye scan can open the general's room. So go to the general at the Control room glass enclosure and scan him.
Also, just use one thread per game - it really helps us if you do.
Lise,
I will send you my saved games BUT they are all after I finished each of those rooms. You can try just to look and see if these saved games can get you to go through the scanners.
