Reply to Audio 10 timecode issues = a little please :)

My new Audio 10 landed today but she's (or possibly Traktor) being an awkward blighter!

All seems normal at first, computer selects Audio 10 as sound device and works perfectly. Open Traktor, load a deck, hit play and works as you expect. But when I attempt to use timecode it won't calibrate, the timecode signal strength bar fly's up, indercating a strong signal but then it won't calibrate? I've gone down all the ordinary avenues, all cables, needles checked and re checked over and over, all nesseary hardware drivers installed and up to date, restart Traktor, computer on off, blah blah blah .....

I've then re hooked up my Audio 8 and timecode works fine. I've since tried "2" of my friends Audio 10's and the exactly same problem arises and my Audio 10 works fine on there Traktor, which for me narrows it down to the software.

For once I'm sure it's not user error (hmmm) anyone got a clue what I might be doing wrong?

I know the original Timecode records won't work on newly registered TP2, but I've been on Traktor for a few years now, alas it's the only thing I can narrow it down too, here's a pic of the evidence.
