VirtualDJ - Problem with controller detection (cn)

Hey I need some help.

I have a Hercules Dj4Set controller that i've been using with Virtual Dj on two different computers for a while without any major issues. But now all of a sudden Virtual Dj can't detect my controller on one of my computers. (it works fine on the other)

The audio works tho, I get sound both to my speakers and my headphones through the controller but none of the controlls work and it's not showing up in the controller menu.

I have tried everything i can think off.

Checked that my licence is active and payed for.
Tried all different usb ports.
Checked for driver updates.
Uninstalled and reinstalled the drivers for the controller.
Checked for errors in the device manager.
Removed any mappers.
Made sure there was no interference with any other midi/audio devices.
And even unistalled Virtual Dj, removed all files and then reistalled everything, and it 's still not showing up in the controller menu.
Now im stuck and i have no idea how to proceed. Anyone know what the problem might be?
