First post here, be gentle

So I installed the KORG updater and sound librarian soft for Windows, went through RNDIS driver update which went ok. What I'm struggling with the USB MIDI driver, though? I'm running Windows 7 64-bit and neither of the above programs can see the wavestate, all I get is 'Waiting for device' screen.
I use a USB cable to connect as advised.
Cheers!
