MY YAMAHA CLAVINOVA CLP-260 NOT RUNNING IN MIDI PORTS WITH REASON

Hi, I have a Yamaha Clavinova CLP-260 (with 2 midi ports, in and out) and I use that in a new Mac Pro with a Reason 4.0.1 program (to compose music), but the keyboard doesn't sound now. I was use the keyboard since 5 years ago in the same program with no problems, but now, when I have the Reason 4.0.1 in that Mac with Snow Leopard system my Yamaha doesn't sound. I use a USB Midi Cable and it figure in a midi options of the Reason Prefrences, but the USB Midi Cable doesn't they lights on.
I don't know what happened. Maybe the keyboard is too old or the control surface of the keyboard is too bad or the Reason doesn't run very well....
Please help me
Thanks
