Reply to S4 right jog wheel problem

Yesterday I got s4 i calibrated both jogs i had little trouble to calibrate right jog because it always showed me errors but I succeed, and yesterday everything was fine but today I tried several times to restart s4 and my mac but every time right deck(deck B and D) freezes, when I press play or cue button nothing happens than i move jog and press play than it plays song for few seconds and than freezes again, i recalibrated several times but nothing happens. Here is the video of some guy that had same problem as I have http://www.youtube.com/watch?v=2o3q2...eature=related . So what should I do? I heard that I should remove platter and than put it back and recalibrate that jog wheel, so if that's solution please explain me how to remove it...
Thanks in advance!
