Me and my friend completed part one, and can get the console for part two going fine but usually around the second or third symbol no matter where I put it the bulb won't light up. Both of us know how to do the puzzle and my friend even completed it before. Why won't the bulb show up? We are both putting the right symbols in the right places (and using trial and error) but nothing happens.
Complete part one of the puzzle Do part 2 normally Partway though nothing you do will progress the puzzle
