I wondered when he said button 5 didn't make much of a difference, that should be the defining line. Ok here we go, try this. First turn all of the lights off, now go to the top of the room, go to where you enter the room from the first puzzle, not the floor, top of the ramp. Got that? ok so now, start to run down the path, as you pass the buttons, don't press the first one, keep running, when you run by the 2nd button, press it, when you run by the 3rd button, press it. Now you have pressed 2 buttons, and are standing in the 3rd small balcony looking thing, run down the ramp some more, dont press the next button you pass, keep running, now press the last button. This is the 2,3, and 5 combo. You should see the path to the center of the room.
If this doesn't work, send me a message with yor KI numer (the KI guide at Guild of Greeters will shoe you where the KI number is located), I've got some technical issues right now, so I wont be able to help you right away, but mabye it will make sense if you actually watch someone do it.
And hey, don't get too upset when something isn't working. It's part of figuring out URU. Just learn as you go and try to have fun!
