Hi there!

I'm playing Penumbra: Overture. Unfortunatelly i got blocked by a problem somewhere at the beginning. I tried to look into several walkthrough, but no one of them dealt with the issue. Are there any known bugs in this game?

My issue: I'm near to the Iron  Mines, in fact I'm in the Auxiliary Shaft where the huge digging  (drill) machine is. There is a control panel i should connect with the power supply. But even if i connect these two things the control panel doesn't get electricity (I've watched a walkthrough, there the control panel lighted up when connected to the power supply). 

I would appreciate any information. Thanks!
