Yeah, I get an error (1009) which to say the least is quite ambiguous. Even googling the error doesn't give one much to go on. And I noticed as well that there is something very suspicious with the contact button. Once pressed, disables buttons 1, 2 and 3... leaving only button 4 as operational. However, press button 4 and the remaining buttons become active again. If it were me I'd probably start over... creating something functional before creating something graphical. But hey, that's just my approach.
