My uncle had this game and he and the rest of my family would get it out around the holidays to play it. Unfortunately a problem arose with the Tower and it has not been played now for nearly 12 years. I recently got it out and found that the tower will not stop turning, I can't seem to fix it either. I took the Tower completely apart cleaned up the motor and gears and then put it all back together and it still wont stop turning. Also the tower display shows 00 then it flashes --

Any help would be appreciated, I know that gamepart.com offers to fix it for 60 or 70 bucks but if I could fix it myself I would rather do that since in my opinion thats quite a bit of money to put into this game.
