I've had the same experience with my 680, the little circle next to "Please wait" keeps going around and around. Once I got an error message about the update file not being compatible with the 680 firmware, whatever that means. My solution is to launch the local software and use that to update the remote. It will check any changes you've made both locally and on the website and update the remote. It also updates a lot faster and you don't have to sit there waiting for the dialog box that asks if you "Want to download this Harmony software" that comes from the website. I've gotten so that I use the 7.2.0 software for all my updates except the settings that can only be reached on the website, even then I use the local software to update the remote.
