Hercules Rmx with Mixvibes 7 HOME no sound through headphone

Hi,
I just bough a copy of Mixvibes 7 HOME to use with my Hercules RMX. I've used Mixvibes in the past and prefer it to the Virtual DJ which came with the Hercules. However I'm having some issues setting it up correctly. The MIDI controls work fine but I can't get any sound out of the headphone jack from the Hercules. It works with VIrtual DJ so its not a hardware issue. Also I don't get any of the buttons lighting up yet I do with the DVS demo [but still no headphone signal]?
Can anyone help?
Thanks
