Korg Zero 4+TSP2 Bugging In FireWire Mode????

I Recently Piked Up a Korg Zero and was very sastified until.............
I upgraded from a 2007 unibody macbook to a 2012 i7 macbook pro updated the firmware, Bought a new firewire cable, download traktor zero adapt, got traktor running with it at home timecode everything ran great!!!! so packed up my stuff and headed to deception #1 setup everything then during the gig boom the mixer starts beeping all iraticly then, No more sound starts beeping again so i shut it off and unplugged my usb no more problems.
I thought i had fixed it because i it ran @ home again fine so i messed with samples rate a bit put it down to 512 44100 so packed up next gig same thing so then put it down to 128 44100 and @ the end of that gig it did the same again so ive been backing up with my audio 8 but would like to get this problem fixed can n e 1 help me out??
