What firmware are you using? ie something they provided, or latest from the internet
To me it looks like the board type you selected simply doesn't have the lcd pins defined is the relevant pins.h
eg from ramps.h
#define DOGLCD_A0 44
#define DOGLCD_CS 45
But in pins_MEGATRONICS_3.h these are not defined.
no idea on what pin out you need though.
