I'm having issues getting my HAT to work. I've downloaded the newest release from Avaya's website as well as an older release and neither are working. When I drop a phone in the cradle, it'll try to install the USB drivers but its unsuccessful. I've attempted to uninstall the HAT and reinstall it both on a windows 7 and windows xp computer but neither has worked. If anyone knows how to get this up and running, it'd be greatly appreciated. Thanks.
