Instructions
Load Splinter Cell and play through the game until you reach the CIA level. Play through the CIA level until your objective is to access the CIA mainframe.
Head down the stairs to access the mainframe before you enter the room with the turret. If you are in the room with the turret, then back-track to a room with a large number of computers and look for a door with a greenish-blue tint. This is the room you need to enter to find the server.
Head back to the room with the turret through the door behind the turret and the elevator should be active.
Load Splinter Cell and restart the mission. When you have to video tape the elevator, then it will appear as its supposed to and you can record the conversation and continue the mission.
