My TomTom won't update and I thought it was a corrupted file on my computer. I then wondered if I never used it with Win 10 so I came to the site to check if I needed a newer app. A message said the Start40 is no longer supported but all others with lifetime maps still are. When I signed in, it shows I have the Start40 but I have the Start45 / lifetime traffic / lifetime maps. I see no way to update it. I wanted to use this tomorrow.
