Carminat TomTom not updating?

I have a Carminat TomTom memory card that I want to update. I have installed TomTom home on my Mac running Big Sur. The program recognizes my memory card, but when I choose the Update button, nothing seems to happen - it goes to a new window with a small icon that looks like an update icon, but without any visible action or progress. What to do now?
