Reply to Help please....Midi Fighter ain't working

Hi,

Just got my Midi fighter yesterday,

I've connected it to my Mac and sometimes it lights up sometimes it wont light up.

It seems like Traktor (1.26 ver) isn't picking up the Midi Fighter even tho I have installed all the mappings needed.

I have noticed that it does not show up in the drop downs menus for the In port and Out port lists in the control manager window.

Some help would be nice.

Will
