I have had a CM11A up and running well for several years. This week, for the first time in over a year, I tried to change one of my timers. The 1.42 ActiveHome software will no longer find a "valid" COM port. Why? How can I fix this?
I have verified the serial COM port both card and drivers (uninstall, reinstall). I have reinstalled a fresh copy of AH 1.42. I have changed the batteries in the CM11A. I have reseated the wiring. I have tried to change to a different COM port known to be good. Nothing (yet) has worked; 1.42 still says no valid COMs are available.
My computer has Windows 2000 Pro kept automatically at the latest levels.
I'm guessing that one of the Windows 2000 updates somehow did something that the 1.42 software doesn't like. But what? What can I do about this?
The CM11A continues to partially work with its contained program, but has lost part of it. This is probably because of my unplugging and changing the batteries. Since I can't get to the CM11A because of the COM port problem, I can't fix the uploaded program.
My house is all messed up. Back to manual, until I get some help. Bah.
Should I bite the dollar bullet and go for a new USB-connected unit?
Thanks for your help.
