Reply to USB interface and Handle Failure...Help?

My midi fighter (received one week ago) won't trigger any effects in traktor. I have followed the steps for setup and I am using the instant gratification mapping. When I downloaded the MF utility program and ran an "update" everything seems to be running fine until it gets to "cleaning", "USB interface", and "USB handle". It comes up with a red "X" beside cleaning up. The there is a yellow "!" next to USB interface and USB Handle. It says "Failed to release USB interface: -6" and then says "Failed to release usb handle: -6". Every thing else on the utility checks out fine. What is the problem? How do I fix it?
