DJay Pro Demo not working with Numark Mixtrack Pro II on Windows 10 64 Bit.


I just installed DJ Pro Demo 1.027457.0 on my Dell Inspiron 17 laptop (Core i7 processor, 8GB Ram, running Windows 10 Professional 64bit build 1803). I started it up and logged into my Spotify Premium account and then plugged in my Numark Mixtrack Pro II midi controller. I got notification that it was set-up and checked the midi confiuration in DJay Pro demo and it showed the Mixtrack Pro preset was selected. However, though my Mixtrack Pro II is lit up it does not work with DJay Pro Demo. I can run the software with my mouse but not the midi controller.

Please advise how I can fix this as if I can get it to work I will buy it.
