Go grab yourself
http://www.nirsoft.net/utils/myuninst.html . It is a free tool.
Run it and uninstall the connect software from your machine. If this doesn't work just delete the entry from the myuninst list.
Once you have done this, you should be able to install the eBook software that you can download from the Sony site. This should update the driver. If not you can update the driver from the Device Manager.
Apparenlty Sony techs don't know much about PCs.
Worse comes to worse you can remove the driver from the registry and reboot.
