Reply to Timecode issue

Ok so trying setup TSP2 with vinyl timecode through the s4, just using basic 2 chans atm 1 for each deck.

Got them plugged in etc got timecoded vinyls on decks got 2 tracks in traktor ready to go. In pref in Timecode setup if i spin the decks i see movement on the channels etc.

I cant get traktor just to start playing when i hit play, even the old virtual dj used to do this, ive been playing around for 2 hours now cant get it working :s

what am i doing wrong!
