Check to make sure that your cRIO modules are in the right slots and that the cables connecting them to your digital sidecar have a proper connection. If you want to be really ardent, you can try checking continuity between each pin using an ohmmeter. You might want to ensure that all of your wires are connected properly and that your sidecar is receiving adequate power. Our team had a similar problem and replacing the sidecar ended up getting the Robot Code light to finally turn green.

It's more than likely a wiring issue than a programming issue from experience.
