Djay Pro on my Mac is unresponsive to my M-Audio Xponent

I plug in my Xponent controller and the software recognizes it, but nothing I touch on the controller has any effect on what happens in the software. Its been working the past couple months on the new MacOS updates so I don’t understand why it wouldn’t now. The hardware is still good so its a problem linking to the software. Any help or solution would be great. Thanks!
