Newly downloaded Premier Elements won't load on my iMac
I'm using a 15-month old iMac running Mojave 10.14.6
I've just upgraded to Elements 2020. Immediately after downloading I succesfully opened all three components; Premier, Photoshop and Organiser. I carried out a couple of quick checks and edits then exited all of them. When I returned shortly after I was again able to reopen Photoshop and Organiser but with Premier I could get no further than the welcome screen. When I click on the Premier icon a message with a spinning wheel appears stating that it is opening the Adobe Premier Workspace but, after a minute or more, the message disappears and only the welcome screen remains.
I should add that when I was able to open Premier that first time I then loaded a project I had been working on with my previous Elements, version 13. The project loaded successfully and I experimented with a couple of quick edits. They went OK but when I tried to use 'Audio Gain' and 'Normalise' Premier crashed.
Any suggestions as to how I might be able to open Premier again - and keep it open? Should I re-attempt the download? Thanks for any ideas.
