Thanks - haven't had a chance to update.

Recovered the password - it was a CAPS-LOCK issue, in reverse.  Unique password that works only with CAPS-LOCK "ON".  Don't know how I messed that up when I set the system up in June.

I shut the system totally off for an hour via dashboard and restarted - all is well, now.  First time I've had any issue with my units.

In any event, I appreciate your suggestion about the power supply and will contact customer support.

Have a nice weekend - or what's left of it.
