Reply to Traktor & Launchpad not on speaking terms!!

I'm in desperate need of some help. Since moving from Ableton to Traktor 4 months ago I've had a beautiful looking launchpad sitting and collecting dust. Recently had some success mapping my LPD8 to control hotcues on decks c & d and thought I'd have a go at mapping the launchpad to do the same thing and run it along side my digital jockey. Seems that mapping the launchpad is a different beast. I've tried automap but that program sucks and I just can't get my head around katapult at all.
Traktor is recognising that the Launchpad is plugged in because when I add a device I can choose the Launchpad for the in and out ports but it's not picking up any midi signals and I've been fiddling with it for a week!!

Can anyone offer some advice because I'd love to add this to my set up!!
