Z2 won't calibrate time code vinyl

I've had the z2 for a week now and absolutely love it but I just came to turn it on and my time code vinyl won't calibrate... Absolutely nothing on both decks, it just says waiting.

Any ideas please? This is scary.

Oh an I've checked needle, USB cable, mixer routing. Tried both USB ports, tried another lap top, tried an older version of traktor and nothing. Not good. : (

 

Is your input routing set properly?

 

Yeah it's all set just as it always has been.

Well....I didn't change anything. Closed everything down because it was to upsetting, restarted my lap top an hour later without changing any settings and boom it worked fine. Just one of those things. I'll def be taking back up to any gig though. I still imagine it was a fault with my lap top and not the z2.

 

I've had mine clear the input routings a couple times, which would give me the same message and wouldn't calibrate. After I corrected the settings everything was fine. Might be a glitch of sorts.

 

Hello,what settings did u used to work?
