Had 2 devices registered on Garmin Express. Tried to add a new device 2 days ago. Recognized device and serial number but said can't add device because our servers are unavailable at this time. I uninstalled GE and installed updated version 7.13.1.0. This time GE won't add my new device or my old devices. I followed all the instructions on garmin.com related to this issue and it still says servers unavailable. I am on windows 10. Any ideas?
