My old 650 was breaking up, and the software wouldn't let me control volume with my new receiver (could see option to select, but couldn't control menu to get it to select).
So i purchased a new One and tried to start over. I deleted the old Windows software and installed new from the myharmony website. Well, the setup routine assumes i have a 650, and doesn't recognize the Harmony One plugged in. i don't want to go down that route again.

i searched Google and Logitech support site, but haven't found my situation.

Anyone have any ideas of what i should try?
