A couple of weeks ago I downloaded the recent sony software very reluctantly, because I wanted to download one of their freebies.
Alas, the b.... thing won't work.
When I try to import files I'm given a pop up box which says: "BTree duplicate key!".
What does this mean? The book isn't already in the software.
I'm considering using calibre instead. Up till now I've used this only for conversions. Will it be able to send books to the SD card in the ereader? Will it mess with my collections?
