I spend much time with the TT tech support, including supervisor (2d level support). The second level person, was more civilized than the lower level people, and really tried to be helpful, but wound up blaming it on an inconsistency between updates of apple and TT. She also thought Mohave OS came after Catalina, which is not correct. She said they will get back with me in a week(!). Not very helpful in fixing their own product.
Anyway, thanks to these last few posts above I solved the problem, easy once you know. For a techie, it seems that a Plist problem should be a fairly basic fix to diagnose.
Thank you so much guys! It's crazy that the TT support does not even monitor their own community support pages.
