Although I'm new to this, I wired it in this way using the Molex connectors and I made sure it they were connected in this way:
(I had an engineer friend wire it for me with a breadboard but i'm now making the direct connections from the arduino board to the matrix.)
#define CHIPSELECT 10//ss
#define SPICLOCK 13//sck
#define DATAOUT 11//MOSI / DI
#define DATAIN 12//MISO / DO
As suggested in the code; at the moment we're unsure whether it's the firmware of the delivered matrix or another unknown issue.
