Cross DJ & Denon MC6000 MK1 locked!

Hello, I need help for Cross DJ.
I purchasing a Denon DN MC6000, and I wanted a simple software to mix at home, so I chose Cross DJ!
I downloaded the latest version of the 3.3.9 but unfortunately, the controller does not interact with the software it manages to sound even less!
Obviously I set in the "audio" drivers Asio of Denon and I think that Cross DJ had understand that this cosolle is plugged in, but despite being highlighted in the console all MIDI controllers, including my next have a closed padlock!
Can you tell me what wrong?
Thank You for your help!
