Reply to Korg NanoKontrol 2 not recognised!

Just wondering if anyone out there may be able to help on this one:

I've plugged the NanoKontrol 2 into my laptop but it's not being picked up as a USB device. It lights up, so it must be alive, but that's about it.

The NanoKontrol 2 shows up in Sounds,Video & Games controllers, but it doesn't show in the HID list as a USB device.

Korg Controller Editor shows no connections & no DAW software is finding it (Live 8 or Cubase 4.5) or Traktor Pro 2

I've installed the latest driver tools 1.13 & I'm using Windows 7 SP1 64bit.

I've uninstalled the drivers and re-installed but to no avail.

Any help / advice out there would be greatly appreciated!

Thanks
