tracktor pro & cdj 350 - a major problem

greetings,
im new to the forum
i just got me a new set up with 2 Cdj 350, im working with brand new Mac and Tracktor Pro (v 1.2.6)
unfortunately i have encountered a major problem:
while playing tracks from the tracktor with the cdj players in controller mode - everything works fine, BUT when i switch one of the players to CD mode, the tracktor "looses its soundcard" and the track that is playing in the other deck stops also!
to make myself as clear as possible:
i cant switch from PC mode to CD mode while working. swtiching between modes in deck A, affect the music in deck B also, causing a cold silence on the dancefloor and the TP to crash.

i tried several things,
i called my tech support from the dj shop, they also had the same problem with their set up (only difference is they used PC, i use Mac)

a person from pioneer tolled me that (i quote) : "Traktor doesn't take kindly to having a soundcard removed from use during operation and as a result, crashes. "

why is the soundcard "removed"? if the USB cable still plugged in to the laptop!
what am i missing? i know the CDJ400 dont have the same problem

plaese help

 

bump...

 

I have the same problem with CDJ350 switching from controller mode to CD.

Using an Audio 8... The sound is working but I need to restart Traktor to reuse the CDJ350.

HELPPPPP MMEEEEE
