I think each time you have to close the CLS2sim program besides closing P3D. I had the same problem as you. If I didn’t close CLS2sim, when I started P3D again, CLS2sim wouldn’t start.

Question for you. I keep getting a message that says I am using unregistered hardware and that CLS2Sim will close in 10 minutes, which it does, and then tells me to purchase a license. I purchased my items directly from Brunner, so I can’t figure out why I keep getting the message. Anything you know to do?

Thanks, Jay
