When I installed TT2020 in November, it worked fine under Catalina. Then I upgraded to Big Sur and now it won't work at all. Uninstalled TT2020 and reinstalled. No difference. Even tried opening TT2019 and it won't run either.
I get the pop-up that it's verifying if everything is up to date. Then nothing. CPU Monitor shows it running briefly and then nothing.
What now?
