After installing new Windows Update on Vista computer, Visioneer 9450 USB One Touch 4.0 won't work. Keep getting message- 9450- No documents transferred. I have uninstalled the driver, downloaded new driver and installed but I still get the same message from One Touch. I can scan to Microsoft Office Document Scanning but it takes a lot longer and won't allow me to scan legal sized pages. Any suggestions? Thanks!
