I have been using my AHP with a CM15A since Feb 2011. Recently I had a hard drive crash on my PC and had to reload XP and all the AHP software. I also installed the latest update along with the smart macros. I decided to make some minor changes in to some macros and everything looked like it was working until I tried to "download timers and macros". As I remember there is a progress bar in the lower left hand corner of the main page that shows how the download is progressing. Now all I get is a little icon that when I rollover it just says "downloading" with no other indication what is going on. This never seems to finish and finally when I pull the USB connector out of the PC, the progress bar shows up with about 95% complete. I've redone the download and everytime the same thing happens. I haven't tested the CM15A completely, but some functions are working. Is this a known bug with the upgraded software?
