Quote - Same place in your user account, next to Vue 10.5, there should be a "Send serial" button.

Thank you!  That worked.

Kind of a confusing setup.  When I started the program, it didn't ask me to put in a serial.  It already had the Vue 10 serial I used to download 10.5, and said it was wrong.  If it had been blank, it might have occurred to me that I needed a new serial.
