speakers and headphones

My name is Simão and i buy a DJ controller mixvibes U-Mix Control 2. I have the latest update of software, Cross DJ le 2.2.0.
But i have a problem that i cant resolve. I buy your DJ cable to have 2 outputs, the headphones and the spekears and i follow the instructions. On your site, you say to put on split mono and its ok. But it doesnt work.
Can you help me?
Best regards
