I have tried twice to play this game and I have come to the same fault for the second time. When I get to the second area Imbolt you get to the top of a tower and you come across a "triangular" transporter thats flashing, you are supposed to transport back to the start of the area open the blue "room and then transport back, except I don't , I just stop there ,nothing happens, I have tried pressing e or any other key. What am I doing wrong?

I have no idea if this is a bug, but you might try taking a look at the discussion about bugs in this game in the Steam forums.
