WS467 modules stopped working with CM15A controller

[SkipW]

I have a whole house system with many appliance modules, lamp dimmers, etc.  I have a CM15A controller and ActiveHome Pro Registered software v3.318.  In the system I have a WS467 (no softstart) and a WS477 wall switch modules that just within the past few days stopped working with the CM15A.  Everything else is working fine.  I can control both modules manually and they both modules respond to commands from a mini-controller.  But I cannot control either thru the CM15A.  I tried new addresses, deleting and recreating modules in the software, and removing each one at a time from the power source in case one module was causing a communication issue.  The software is finding the modules.  I haven't tried replacing the modules because it doesn't make sense for 2 different modules to fail the same way at the same time.  Any suggestions?

Have you tried the Mini-Controller in the same outlet as the CM15A?
That would show some possible power line issues.
Any new electrical or electronic devices in the home or an existing devise moved?

Maybe you have a noise source on same line as CM15A. Any new electronic toys plugged in?
