Reply to Behringer ddm4000, mappings!

I've just bought my Behringer DDM4000 digital pro mixer. And a MIDI DIN to USB cable. Now i need to map my Behringer to Traktor pro.

Eventhough the mixer came with traktor 3, i've bought traktor pro because it has 4 decks to mix, the same as the mixer when traktor 3 only has two.

Now please help me here, how do i map my behringer?
Someone please help me fast, because i've got a gig for a school on the 16th of april. So please as fast as possible someone help me?
