Reply to Kontrol Z2 with Denon SC3900 issues please help

I picked up a Z2 a couple weeks ago when it went on sale. I then ordered a Denon SC3900 and it arrived last evening . I was able to get it to work for the most part but I am having some issues.

1st in the Midi Hybrid mode under preferences on the SC3900 it will not allow me to change the PC/MAC setting to MAC. When I turn the SC3900 on and use the midi mode it links as a PC and will not let me change to a MAC. I have updated the firmware and configured the MAC audio/midi setup on my laptop. The SC3900 midi controls (cue points, loops, browse knob, etc) works in Traktor but it will not let me switch from PC to MAC.

2nd the timecode does not calibrate and is very glitchy. If I run the track deck in thru mode I can hear the hybrid timecode signal coming through and changing when I move the pitch slider. Sometimes the play/cue buttons will start a track, sometimes not. My biggest issue is the pitch slider, it will be at zero (in the middle) but Traktor will show it all the way up or down plus it is greyed out so I cannot change it manually.

I have a week before my next gig and would like to use this set up if possible. I do still have my S2 if all else fails.

My current set up is a mid 2010 Macbook Pro running the current version of Mountian Lion, Traktor Scratch Pro 2.6 with the Z2 & SC3900.

Any help would be greatly appreciated.
