got it -- it's still not finding the NC-50. I rreally think I got 2 bad NC-50's! I've done like 3 or 4 factory resets on the NC-50, and then cleared the Zwave config on the Q50 and then gone to "start new Z-Wave network" and it still says "failed" when I do the "find node" routine. I've completely removed it from my configuration in Studio Pro, then done a download to the controller, then re-installed the NC-50, and then re-download to the Q50. Nothing seems to be working.
