Itunes not accessing music on mybookworld

I am trying to access MyBookWorld from Itunes but simply get error "Loading “MyBookWorld”…

I have tried to configure the drive as instructed in the advanced tab but still no joy.  Can anyone explain to me how to do this for the MDL WD20000H2NC.  My PC is running Windows7.
