These seem to be entirely Windows related. I'm on a Mac. I have used TT since 2014. It always worked once the access code was entered so I never saved them. However, today I tried to start both 2020 and 2019 to check something and it asked for an access code. I had those codes originally but they are long gone.
I have a new computer and I am in a different location from where I originally used 2019 and 2020. Either could be a factor. I tried turning my FireWall off but that didn't solve the problem.
