Problems with mixer

Hey guys,
Just joined so I'm not too sure if i'm posting this in the right place. Anyway, I have just purchased Cross DJ in the hope that it will go well with my CDJ 850s. Everything was going great and I was very impressed with the connectivity between the two until I realised that it was only coming out of one channel on my mixer (DJM 700) so I couldn't actually switch between songs unless I used the faders on the software.
I'm guessing this is an output routing problem but i'm not the best when it comes to that so any help from you guys would be greatly appreciated!
Thanks, Charles.
