No licence for my virtual instruments message on start up of Cubase 12 Mac

Recently I’ve Benn getting a dialogue box coming up when I start up Cubase 12 pro saying that the following licences cannot be found! If I then quit Cubase and run the E licenser and then restart Cubase it opens correctly with everything loaded ok. Mystified!
