Reply to help with numark mixtrack

I have a numark mixtrack controller and I usually pair it up with audio2dj on my laptop.
I was using tracktor pro and then came one day when I plugged the controller into the usb port and started traktor, but the computer didn't seem to recognize the controller anymore.

At first I thought the controller died on me, but I tried connecting it to my other laptops and computer and it worked. So I assume the problem lies with the current laptop.
I tried changing the ports but it didn't work.
I tried resetting the usb ports in the device manager but it still didn't work.
I tried re-installing traktor but it's still a no.

I'm at my wits end.
Appreciate some help.
Thanks!
