I cant get ur22 & cubase7 to record my dj sets

Hello Steinberg Lounge

I just purchased a ur22 audio interface and I cant get the Cubase 7 to record my live dj sets. I am more than certain its the hardware im not plugging in correctly.

I have:
cdj2000’s and a djm900.
qsc kw 153 powered speakers.

Could anyone show me the way?

Thanks everyone.
