Re-wire Ableton Live

I’m a running Ableton Live 8 lite. I have constructed a live track/set that I want to incorporate/insert to an existing track on Cubase 6. I have set up the re-wire funtion and both programs are talking to each other however when I hit record on Cubase the track does not ‘record’? There is a signal and I can see & hear the Live track working fine but I can’t capture the audio? I am assuming I bus the live track on to an audio track in cubase? Can anyone help here?
