Maybe your getting crosstalk between the breadboard wires. Keep the DIN, LOAD & CLK short and if possible away from the SEG & DIG wires.
It could also be power related. Ensure your PSU can deliver the power needed. Maybe setting LED intensity to 1 lc.setIntensity(address,ledIntensity) or increasing IREF value will allow the sketch to run and you would then know problem it's power related.
