While playing SOC I run into a bug that prevents me from getting past the x16 lab. When I go to shut off the brain scorcher the button does not work no matter how long I hold the use button.
The only relevant info is that I am running this on windows 7 x64 and I got the game through steam. I ran into the exact same issues with XP x64.
Are you sure you activated each switch as you made your way up?
