Reply to Connection problem S2

Hi!
I need help!
I just installed dvd which was with S2 kotrol. I did everything from Setup guide. But when i plug and turn on S2 the usb indicator is blinking. The mixer is working and some other knobs (i can see this on monitor), but i can't to load most of tracks and the knob Play doesn't work and other knobs looks like work incorrect.
Do you have ideas?
