Hello, I’m a mac user and I had the same issue with Cubase 11 Pro after re-installing my whole system via time machine. I kept on noticing that my Ilok logging wasn’t popping up since I have plugins that requires it for authorization. So, I’ve open the ilok manager program, logged in, activated the ilok cloud and restarted Cubase 11 Pro and that did the trick. not sure if this will help anyone but I thought it was worth mentioned.
