I got the padkontrol yesterday!

And installed all the software and everything was done the right way.
But I get this massage @ "device manager" that says:
"This device cannot start. (Code 10)
Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available."
So I did, and I got the answere that the device is up to date and so one...
The PK showes no light on the dispay and dosn't start at all...
What is the problem and what do I do? :'(
Thanks for any answers and help in advanced!
