Jog wheels problem :(

Hi everybody,
I dont understand why Cross DJ (version 1.7) was perfectly running on my old PC with Windows and now that I have installed the last version (3.00) on my new MACBOOK PRO, I have big problems with Jog wheels...
When I use JOG WHEELS, it doesn't scratch the song but it changes the pitch bend (I have checked that I'm in vinyl mode)
Can you help me please because all the buttons work properly appart of the Jog wheels !!
HELP HELP THANKS !
