New Denon SC 3900 CDJ's

Hi Everyone,

I'm new to this forum, sort of new to digital DJ'ing and am hoping you guys can help me with a situation. I just purchased two Denon 3900's to go along with my Allen & Heath Xone 4D. I use Traktor Scratch Pro 2 with an Asus 17 inch laptop (2.3Ghz I7 Quad core; 8GB ram). The problem I'm having is I can't get the CDJ's to control the play function in Traktor nor will the platters work to scratch. I'm supposed to be able to do this without the time code CD's.

I have my rig set up as follows: left deck midi channel 1, right deck channel 2 and mixer channel 3. I use inputs 2 and 3 on the mixer. All midi commands from the tsi file works except as explained above.

Any help you can give me will be greately appreciated.

Thanks,
