So i am in day 5 i guess, and i am on the sesen, and after i find the 7 simbols in the cathedral i go to this place i have to get into the headmasters office, but its locked and i cant find out how to get in there, and, if i leave the place thru the map, i cant come back. How do i open the headmasters office door (where is the keycard?) and how do i come and go from the secret chamber?

SPOILER

To get into the headmaster's office...


Found the storage room with the monks' robes?
Look on the floor by the robes - Keycard!

THANK YOU!!

I am on day 9 and I have fixed the reactor and exited to the Atrium. I have passed the blue ball of death and climbed the stairs to Level 3 (second floor).

But the door is not live and even though I get the 'operate' symbol with the cursor over the door (or screen panel) nothing happens when I click.

Any ideas anyone?
