(I had the same problem-only one of my programs would work, and the rest of the buttons (even start) would not work. I used some scissors and carefully cut about a 1/2 inch in the plastic inbetween each of the copper strips in the ribbon cable. Then I seated each one individually (put them back in the white plastic thing) until I found the one that was freezing all of the other buttons up. Now all of my buttons EXCEPT for the one that was working before work. I can live without 1 program if it saves me $300) - This answer solved my exact same problem. Thanks so much!!!
Thankful
