Cross DJ & Hercules RMX set up help please

Hi All
Just bought a Hercules RMX & am having trouble setting it up properly with Cross DJ 3.3.10. Hope somebody can give me some advice.
The software has detected the controller and everything lights up. The stop/start controls, cue, wheels & pitch control are working for both channels through the controller but deck volume controls aren't working & only the left channel (Deck A) is audible through through the external amp/speaker set up (Denon amp & Tannoy floorstanders). The software is'nt showing any volume controls or crossfade on the laptop screen so I'm not sure if it's a mapping or software or controller issue.
Here's a pic of the audio settings:
Any help would be most welcome.
Cheers
Steve
