Reply to Audio 6 Not Connected... it's plugged in and lights are flashing!!!

Hello Chaps,
I have Traktor 6, but I also have a Denon DN-X1600 mixer, so I don't usually need the Audio 6 that it came with.

I have a gig in 2 weeks, my 1st gig for 3 years and I need to use Traktor, problem is as follows...

I installed the latest driver, then I plugged in the Audio 6 (the Audio 6 lights up and the green USB light starts to flash), as soon as I do this, I get a message in my System Tray on Windows saying, "Installing Device Driver" or something like this, every time it fails to install properly (but I figure that this doesn't matter because I have manually installed the driver), then I open up the Audio 6 Control Panel and it says...

"No Traktor Audio 6 Found Make Sure That The Interface Is Plugged In"

So, I tried various things with the driver and also swapping USB ports but still it makes no difference. I even tried to open up Traktor which works brilliantly with my Denon Mixer, but it won't recognise the Audio 6, so I can't use it.

I have also posted the same thread on the NI website, but it's not often that anyone on there can or wants to help. If anyone here knows what to do, or can offer me some advice I would be eternally grateful.

Cheers, Dan.
