Reply to BDC 3000 issue

Hey guys, i recently bought a BCD 3000 from a friend and im having a problem with it; my "key deck A+B" and "cue A, cue B" buttons are not lighting up hence not working. When i test the midi controller in the midi set-up, the buttons are functioning (a noise plays indicating that the button is working). im assuming that this has to do with how the mixer is set up in vdj. im running mac and vdj 5.2. Any toughs and comments would b greatly appreciated, thanks.
