Overture Refinery issue

[NightOwl]

I'm having the exact same problem, too. I watched the YouTube walkthrough videos and thought that I must have forgotten to do something somewhere. Then I read the online walkthroughs. None of them say anything about having to do something to get the little hand icon to appear over the controls in the refinery. It's just supposed to work. None of the buttons respond when I use the space bar to activate them, either. Then I find that I'm stuck in that miserable room and can't get out!

By the way, I bought the Penumbra Collection from Direct2 Drive. Dunno if that matters. I hope someone will provide an answer.
