So I updated Safari 10.0.1 from Apple on October 25, '16 (bug fixes and improved security). I went to upload data from my Forerunner a couple of days later and tried to open Garmin Express. It opened for a couple of seconds and then closed. Lost all data of my workout. The Safari update is the only change that I can think of recently but no problems ever with Safari/El Capitan until now. Downloaded Garmin Express a couple of times but still happening (opening for a couple of seconds and closing). Any ideas? Thanks!
