Good morning, My son is 11 yo and has been using his Bookport mainly for listening to music and a few stories. I have recently signed him up for BookShare.org and we downloaded the first file this morning. We downloaded a .BRF file and copied it to a CF card using a flash card reader/writer. When I attempted to start the file I got a message that said "Playing unfiltered files not supported" I thought that perhaps I needed to use the Bookport transfer software so I deleted the file and reloaded it using that. I got the copyright warning file fine, but I still can't access the book file and get the same message. This has happened in the past when we have transferred stories that were written on the BrailleNote and stored in .BRF format. We are hoping to be able to store the files on a CF card so that they can be read using the refreshable display on the BrailleNote and listened to on the Bookport. Are .BRF files not allowed? To do what we want will I have to store two versions, a .BRF for the BrailleNote and a Daisy file for the Bookport? Any help would be greatly appreciated. Blue Skies, Dave
