I am the owner of a Canon CanoScan N67OU and I am trying to scan documents onto a Windows XP computer. I downloaded the TWAIN driver, which the scanner said I was missing, required to install the CanoScan toolbox. When I try to scan documents, though, it shows the error "Unable to select TWAIN source".Can anyone please help me? What can I do?

Thank you,
