Hi, I've recently run into a problem where I use BBC Symphony Orchestra Discover by Spitfire Audio. I have two different computers that I use to work on and I can no longer switch between them because the other computer would report that the "synth rack is missing" or the plug in is not found even though I have BBC Discover downloaded on both my computers. Is there a solution to this? I am quite new to audio sequencers.
