U-Mix Control Pro Audio settings issue

Hi. I'm using U-Mix Control Pro. On audio settings of Cross DJ if i choose "Mixvibes Asio U-Mix Control Pro" i cant even load the music to the deck. it says "can't load. check your audio settings". What should i do?
Another question: My headphones are connected to U-Mix Control Pro device. And the Reference Monitor is connected to my laptop. i cant get any sound on my headphones. Again. i think both of these question got only 1 answer
BTW the users guide is so low..
