Good afternoon: I would suggest that you download the files again from Web Braille. I got the same message you are getting even though I have Windows XP. I erased the files from the computer and downloaded them again. After that I was able to load the files to the Bookport. Hope this helps.

The software on the book port is 2.3.0.0. I am using Vista which has the latest updates. When I try to move a web Braille book, I get an mfc (Microsoft Foundation Class) failure. Questions: 1. Should the book port software and file transfer have the same version? 2. Have others been able to transfer web Braille books using Vista? Regards Louis Maher
