Reply to VCI-100 Problem

Hey, I need some serious help.

I have a VCI-100 I use with Traktor le. I had it working on my laptop that was running windows xp fine but thats has recently died. I have now re-installed the Traktor on another computer, that is running vista. For some reason traktor lets me see the vci as a controller, but wont let me click on it so it works. please help me.
