Donald: Have you also updated your firmware? I doubt this is in any way related to RFB&D. When you say, "it's garbled," do you mean staticky or something else?

I installed software from RFBD, so I could listen to their daisy books, and shortly after that, (a week or so), The bookport stopped playing MP3 files properly. They sound like garble now. I've tried deleting the files, and re loading them, and regardless of the type of MP3 file I transfer to the bookport, it doesn't play properly. I'm running the most recent software update; All other file types play just fine, even the memo files, but not MP3 type files. any ideas about what could be causing this? Thank you for your help Donald R. Bowman
