ion DJ and mixvibes headphone problem

hi i have just purchased the ion discover DJ and loaded up the mixvibes software. i've also installed a usb 5.1 sound card.
Problem: Cant get the right config to have it work as expected.
Excuse my terminology from this point on...
I want to be able to have the music play from my laptop speakers (for now) and be able to monitor(?) the other track from my headphones and effectively mix via this method. Listening to the music from the speakers and then the other track on my headphone and simply mix/cut it in using the Cross fader. Simple and normal request?
If so, I can't seem to get that config to work on my laptop.
I have tried all the settings but none of them work.
Are there any steps I can follow for this?
Thanks
Imtiaz
