Here's a new one for me. Suddenly I'm not able to launch Raven. I get an error message telling me too many DAWs are running and to quit one. In fact I am only operating one DAW, Pro Tools 2019.5. I have used it with Raven successfully for a few days. Today it won't work. I have tried quitting and relaunching Pro Tools. I have tried rebooting the computer. Still having the problem. Any ideas?
