Help with Ableton Live Midi!

I have been using traktor 2 and ableton live for ages now however after not using for a week or so I have come back to find that my midi controllers are not sending midi out.

I have a Akai LPK 25 and a reloop digital jockey 2 interface edition…

The inbuild sound card works however none of the controllers work…




is your midi controller showing up in Ableton?
