pedals command

Good Morning to All

I have a Yamaha B3 sient piano connected with a midi usb cable to my laptop ( windows 7 prof )
Suddenly pianoteq doesn't receive the pedals commands, all note are working
I've tried two differrent midi usb cable, plug and play, no driver necessary
Reinstalled pianoteq, update the driver of the sudio board ( realtek )
Nothing to do : pedals do not works in pianoteq but, if I play the Yamaha stand alone in silent mode the pedals works
Someone can help me ?
Thank you in advance
Antonello
