Traktor LE + Total Control - Audio ROuting issues

I just bought a Total Computer DJ in a box (basic) and am very new to Dj;ing. I am having problems with the audio routing. Some specs are as follows;

I have a Windows 7 system and I am getting good sound out of the outputs into my speakers

The problem arises when I need to monitor – I am hearing the channel B tracks on the speakers as well as headphones

I have set up exactly as the user guid has indicated and have the Monitor to outputs 3 and 4 and the Master outputs to 1 and 2. (in Internal mixing mode)

In External mixing mode I have Output channel A to 1,2 and Output Channel B to 3,4

This is using the DJ I/O product from Nuamrk along with the Total contol and Traktor LE. Anyone have any dieas how I can get to hear what’s going on on channel B while my cross fader is towards channel A without it blasting off (no matte rwhat position my crossfader is) on the outer speakers?

I feel like it’s a small tweak and I have tried ALL combinations of input – output routing.

Is there something in the service center I need to download?

I just want to mix and monitor – simple problem
