driver for Sony BP-ICD 150 digital voice recorder

I recently upgraded from xp home to xp professional. It
appears most things transfered over except the driver for
my Sony BP-ICD 150 digital voice recorder. When I plug
it into the USB the computer does not acknowledge the
recorders existance. Does anyone know where I can locate
it or what I hsould do? I do not want to wipe my drive
clean and re-install if I do not have to do so.
Thanks.
