Arrived home today to discover that AHP could not find the CM15A (I turned on my Living room lights by the SS13 inside the house at the front door) so I shut down the PC and unplugged the CM15 from the outlet, opened the battery compartment and took the batteries out, got 4 fresh ones and put them in, closed the battery compartment and plugged the CM15 back in the outlet.
Rebooted the PC, checked the Hardware Configuration and made sure the CM15 was seen by Windows, opened AHP and made sure it saw the CM15 (it did) and tested various modules to make sure full communication was there. It was. I then cleared the CM15 and reloaded all timers and the single macro
The "side attraction" was that the MC460 I use to trigger my lone keypress macro had also died so a new MC460 was gotten from the "X10 Spare Box" and old one got friendly with the trash can. With the new MC460, the macro ran perfectly.
