Okay Mome, I had to replay this part of the game. When you flipped the lever green lights and one red one appeared on your console. Back up one step from the console and face left. There is a board[reminds me of a chalkboard]and it should be lit now. Go to it and click on the blue triangle. Now you should be able to go downstairs and get into the transporter with the module you picked up.
Yesterday is but today's memory, tomorrow is today's dream.
