Yes I do have the book, but not song manager

When I first bought the 256MB Card, I formatted the card on the 7000, and I was able to transfer songs (22 folders at 3 minutes each) from my computer WITHOUT using Song Manager or the SD CardTool. All I did was drag and drop the files from the 128 (saved on my computer) to the 256 using Windows and the Panasonic Reader Writer and they showed and worked on the 7000 and the SDCard Tool. When I tried to add more files from a 32MG Card, it did NOT work.

I'm just trying to figure out why the intial transfer from the 128 card via computer, reader /writer to the 256 card was sucsessful without Song Manager, and then when trying to add songs later from a 32 card the same way, was a failure.

Thanks for the help tips
