Korg Nanopad not working in Garageband since upgrading to Lion

I've just upgraded to Lion and the new update to Garageband but have found that my Korg Nanopad's not working anymore. I've got a Nanokey and that's fine but not the Nanopad. I've Downloaded and installed all new drivers etc... but still no luck and strangely now I can only get Mac to recognise one midi input at one time where I used to get the ability to run two at once in Snow Leopard. I get the light on the unit and when I tap the XY pad, I see a little dot appear in Garagebands LED area but none of the pads are making sounds like they used to. Not sure if it's a note mapping issue but have hit the frustrated level now.

I'm hoping someone can shed some light as it used to be pluginplay goodness.

Many thanks.
