Hi, I'm in the Castle of Vothkaro and I'm down by the large barrier and at the control panel which moves the traps along the stone floor. No matter what I do, I cannot enter the west room. I've moved the traps all over the place, but keep getting smoked out. I know I need to get to the little switch on the right hand wall, but even when all the traps are on the left hand side of the room, I can't enter. Help!
