This has occurred several times over 3 years and several updates (during events).
I load a track onto deck 2, usually cue it just to check and it will not play. I can load a different song, skip ahead in the track but nothing will make it play. No error message. Deck 1 behaves normally.
Dragging and dropping the track with the trackpad rather than using Traktor worked once but failing that restarting Traktor was the only solution each time. (happened last time during wedding dances, not fun.)
I can't continue using it if this is going to be hanging over my head and I'd love to be told that it's an easy fix/user error.
Help!!
