Thanks Tig. Now I have a different problem. After going down another staircase and over to a console, I clicked on the joystick to see the hologram and then on the book. It opened to show me a box. I went upstairs and located the ring in the wall, clicked on it and the door opened, revealing a box with 5 buttons on the top. I set the buttons correctly and the box is supposed to open revealing a blue and gold crystal key but in my case I get a white screen. What is wrong here?
