DDJ-SB no sound in headphones

Hi guys sorry for posting this here, I just can't post it in the support forums (don't know why).
I bought the Cross DJ software, great software, but I got several problems.
I'll start with the most urgent: I can't get no sound in the headphones. It might be a problem in the controller itself or in the definitions, but I thought I'd ask here maybe someone could help me.
Thanks.
