Last night I connected my oxygen up to use in Traktor along side my vestax tr-1.

I mapped out the keys I wanted to use on the oxygen and everything was fine. I also set the controller knobs to use. I closed traktor down and re-started a little later and the controller knobs would not work? I tried to re-map them but no matter which one I turned it would send the same message as if it was the same knobs I was turning. The keys still worked fine though.

Anybody else had this problem or know how I can fix it.
