LED not working on U-Mix Control Pro

Hi Guys,
as my netbook is bit slow, I cannot use CrossDJ which comes with the mixer U-Mix Control Pro. But my netbook runs good with Traktor 3 DJ Studio and therefore I set the mixer up to work properly with Traktor 3 DJ Studio.
But the LED's are not working, even when selected as MIDI input and output this USB device.
Any advice on this?
Thanks
KC
