Reply to No Sound on the right Channel of Deck A

I need help as I have tried virtually every thing and have had no success.

I have just received my new Mac Book Pro 17 with the new I7 processor in it.
I installed my FireBox and then installed The latest version of Traktor Pro 1.26 and also downloaded the 3.5 TSI.
When I load a track on to Deck A, I get no sound out of the right side at all. When I load a track on to Decks B, C, & D both right and left channels play just fine.
I have Installed the TSI file a dozen times, Even tried the Traktor TSI file for the VSI-100 and still no luck.
I have run out of options and do not know what else to check. If any one has any Idea I would really appreciate it.

Thanks
