SpectraLayers in Cubase 15 Pro Does absolutely nothing - what am I not doing?

SpectraLayers

I have three audio tracks. I select and highlight one. I go to the Audio menu, select extensions, select Spectralayers and nothing.

I have opened the application on my mac separately but that’s not how I want to work, having already set up a project.

Any ideas? Thanks.

Have you tried reinstalling SL?

What do you mean by “nothing” ? The UI doesn’t show up at all ?
Fully delete any SpectraLayers file and folder in the VST3 folder and reinstall SpectraLayers.

Sorry for delay. Yes the UI doesn’t open up in Cubase. I did a reinstall without a previous delete. I can try deleting files first. I had a bad feeling when I installed the 15 update then removed 14. Next year I’ll get a new machine but right now I’m in no mood for a rebuild.
