Little problem with Korg NanoKontrol

[Sputnik23]

Hello,

i've got a Korg NanoKontrol. I'm working on a pc with Windows Xp, and i've installed the drivers and the Korg Control Editor.
I've plugged my NanoKontrol to the PC's USB, and its red light was turn on, that seemed ok.

When i've tried to tune it with the Korg Control Editor, this software "said" that NanoKontrol was not connected...
After reboot, i opened it again and it recognized it. But, after closing it, and after having opened it again, it said again that it was not connected...

i want to use it with Ableton Live, and assign its knobs to Audiorealism bassline control such cutoff or resonance...

Can say me how to solve it and how simply use it with Live please?

Thanks a lot!
