Thank you.
I did all of the offered advice. I can get the project to open and get everything working properly, but it doesn't hold. If I save the project, close SONAR, start SONAR and open the project again, the same problem persists.
I have to remove the FaderPort control surface before loading that particular project, then add it again after the project loads each time. I can make it work thanks to you guys. I just wish I didn't have to do that every time.
I can verify that on new projects this is not a problem. Only on this old one.
Thank you again for your help,
