Are you certain you have the modules installed in the correct order in the cRIO? Starting from closest to the ethernet jack, it should be Analog, Digital, Solenoid. If you have the wrong module in slot 1, it's going to try reading analog calibration values from a digital or solenoid module which isn't going to work.

The other slight possibility is that you don't have the module seated correctly in the slot. It should be pushed back far enough that the two dimples in the locking tabs engage the cRIO and you can't easily pull the module out without releasing the tabs.
