A general rule about any software: backward compatibility. How can I convert old ALL and ARR files to CPR files? Cubase SE3 won’t work because of licence issues. This is a real nightmare. Steinberg: give us a solution to open our old work.
Getting to run Cubase SX/SL 3 is the way to go.
Feel free to cotinue a discussion on that thread. I will close this one.
