Having trouble installing new or changing existing macro's and timers. When I make the change and download, the download takes place but the new timer or macro fails to load (work). Existing macros and timers continue to function properly. I have unplugged the CMA and removed the batteries, purged the unit and reloaded the macros and timers but the result is the same. I now have a fresh copy of the software from Active Home in hopes that this might help but I need to know the procedure to reinstall the software without loosing all the data, macros and timers that I have in the program. I have been told to export files to a .ahx file but am not quite sure how to do that nor how to make use of it after the reload. Any of you experts willing to give some free advice? Thx!
