Stream has on SD card 4 books in Talking Books. C/P them into Books folder in My Documents and then delete them from stream. C/P original 4 books plus others back to SD card only the 4 original books show up in player although card in computer shows them all and they can be played on computer. Any suggestions why this should be? Could it be because I have not up-dated software? 3.3 is available and Humanware talk about up-grade of 3.3 for companion software. What is this? Where do I get it and is it necessary to have? Could it be a problem with the Stream player? I have tried copy and pasting with 2 different card holders but I haven't used a different SD card. Thanks Brian
