Hi and welcome to Arturia forums.
I don't have a Arturia controller.
In Midi Control Center i can see, that there is only a generel Essential setup. I'm not sure you will see your excactly. I believe the differences is only about the keyboard. But i can't tell for sure.
I guess, the error messages you get can be if you have a DAW or another music application like Analog Lab and others open.
Keep in mind, that this forum is'nt official Arturia support, even if they sometime answer here. I suggest you contact Arturia support through your account, if needed.
