Maybe someone had a similar issue:
I just made a project with V4.15 and after saving I cannot open it again, because I get a prompt that it has been made with an earlier version, which is not the case.
The thing is: it contains a Panasonic RZ-projector driver with all (=hundreds) of commands that I all changend manually from AckCommand to Command to make it work in version 4 but I did not export the device, so it is now stuck in that project, that doesn’t open anymore…
My second question is: I don’t see the channels window. I noticed that it has been switched to the devices window, but the coulmn for the channels just is not visible on my system. I’m on Win 10 64Bit.
