[CLOSED] Sep-C1 and Serato

I have SEP-C1, MacBook Pro 10.7 OS,  and Scratch live 2.3.1.  I plugged in the Sep-C1 and it worked amazing.  No mapping required.  The right deck works perfect however the left doesn't work 100%.  Sometimes freezes... press play and the play button lights up on both serato and sep-c1 but does not play (needle does not spin, sound waves don't move).  Secondly the tempo slide bar moves slightly (just enough to see that is does move).  The % moves fully but the bpm does not change and the audio is not affected.  Is there something I'm missing before I return it for a replacement under warranty.  Today its the first day I've tried it.  You can see in the attached screen shot.  Please help!!!!
