Same here. Tried with Mojave AND Catalina. No success. After install, first time it goes through its "verify" process, then warns me that Mojave is ok this year but not next year, then the TT icon bounces a few times, stops bouncing, and TT is not running. If I try to run TT again, it just bounces a couple of times, then stops. Tried the CD version and the download version. Found one posting that explained how to clear out the Library of TT stuff. Did that. Same problem. This is infuriating!!!!
