The old DS status is good enough.

Did you try swapping the cable between the cRIO module and the Digital Sidecar? Use your spare from last year or the new one from this year's kit.

The other swappable component is the digital module in the cRIO.
Have you reset the module in the cRIO chassis?
One more thing to check is to inspect the pins on the cRIO module (both ends) and the pins in the cRIO slot on the chassis to see if any are bent or have metal debris in them.
