You could try re-applying the IO board update from the DS update (uninstall then re-install). Also, make sure there isn't anything shorting the io board (unplug it from the breadboard, check for metal shavings, etc.)
If you need a replacement, most likely you will have very little time to test it, if any. Our team ordered a new one since we lost the kit one and it took at least a week and a half to get here. In the meantime the DS can simulate the digital and analog inputs of the io board through the IO tab.
