Wendy, Wow, didn't know this list was still active. You and I may be the only ones left on the planet still using a Book courier. I use mine mainly for Daisy files and I rarely have problems. Usually the best way to resolve the kinds of problems you are describing is to reformat the card and reload everything. I know that's a pain if you have a lot of stuff on the card, but the files do get corrupted and reformatting is sometimes the only cure.

I always make a number of folders on each card, and limit the number of files in a folder to no more than ten. Sometimes I get an error message while going through the library saying that a file cannot be played. Tonight I downloaded a new MP3 file into a completely empty folder. When I tried to play it, the Courier started it, and then went back to a file in another folder. It doesn't even give me an error message. Wendy
