Reply to SC3900 problems HELP! gig tomorrow!!!!

So got the Denon SC3900's in today. I'm REALLY confused. I downloaded the tai file, and some of the midi controls work, but can get the play button to work, and can't get the platter to move. Do I need Traktor Scratch Pro? Do I need a sound card? What do I need? Need to get these set up for a gig tomorrow evening , and I'm a little worried. specs about my stuff.

Gear:
Mac Book Pro.
Novation Twitch.
Bcd300 (which I'm using as the sound card pretty much it)
Kontol X1.
2 SC3900's.

HELLLLLPPPPPPPPP!!!!!!!!
