Elements 14 Stopped Working on my Mac

I just got a new Mac and moved everything over from my old Mac, inluding Elements14.  It worked initially, but after the first time it wouldnt open any more.  I tried restarting the computer, but it just doesnt respond.  Tech support says that its no longer supported by Catalina and that I have to update to the new version.  However, the program continues to run fine on the other computer.  I don't really want to spend $100 on what is basically the same program and all tech support wants to do is sell me the new program.  Does anyone know a work around?
