please check your board thoroughly because i have made three of them and they work . except you have to do a lot of debugging because the pcb traces are very close.

hi nmos i still insist you go through all the pcb traces again . i faced the same issues because pcb traces are so close together. i had to recheck many times but the pcbs i made all worked after many rechecking and clearing the tracks.
