I get this problem from time to time when the HDHR is power cycled 
and/or the MBE is power cycled usually due to a power outage. I haven't 
figured out the exact process but usually restarting the MBE seems to 
fix the problem though sometimes I have to delete the HDHR and add it 
back in before the MBE will recognize it again.
