HELP!!! i have found the three gears and they are, of course, on the wall and nothing is happening at all. That girl just keeps telling me that i need to find all the gears. I have found all three tuning forks, but not sure what to do with them. Also, where is the last peice of paper with the letters on it. i have been in all the doors with the cides on them and can't go any farther. AAAAAAAAHHHHHHH!!!
