I have just updated to the latest version of Garmin Express. It will not now recognise my 910XT. It says the ANT stick is unconnected even though it is plugged in to a USB port that has always worked perfectly before. It won't work in either of the ports on my Mac. Neither will it recognise the watch when plugged in via the cable. So I have no way of connecting/transferring from the watch to GE. I am using running Mojave 10.1.4.1. I have tried deleting the watch from Garmin Express and completely uninstalling and re-installing GE but neither has worked. What should I do?
