Can't move ttbin file from PC to MySports or Strava
When I tried to sync my latest run, it apparently failed as it did not upload to either TomTom Sports or Strava. Bizarrely, the run I did previous to it (and had not yet synced), synced to both perfectly.
The run that I am missing on TomTom Sports and Strava is still visible on my watch.
Following previously published guidance, I located the file on my phone (via iTunes) and saved it as a ttbin file to my PC (Windows). I cannot seem to make the next stage work though. When I double click the file, it opens the TomTom Sports Connect programme on my PC, but all this says is that the watch is charging. When I go to settings, there is not a 'Try Again' button for me to click on, which is what previous answers to this question say there should be.
Some answers also suggest placing the ttbin file in the serial number directory 'Windows: C:\Users\[user name]\TomTom MySports\[serial number]' - but I don't know how to do this. I need a complete idiots guide! How do I do this and how to find out what the serial number is?
