"No MIDI device detected" issue

I just recently purchased Cross DJ and enjoy it, I am trying to connect my Hercules RMX controller but the interface just says no MIDI detected even though the controller is plugged in via USB and fully on (lights flashing etc.)
I have tried unplugging the controller and reopening the App with power on. Also have tried opening the app AND then plugging in the MIDI but nothing seems to get it to be recognized. It says that my controller is readily available to be recognized
I am sure this is a repeatedly asked question so I apologize if there is an answer for this question.
Thank you
