Hello all. I have downloaded the latest firmware and software updates at the prompting of the bookport transfer software. I have a books folder and I transferred 6 daisy books without incident. I also put a few etext books on and then read some daisy books and deleted them. Now, when I try to add more daisy books, I get a prompt that says .mp3 disk is full. When I check in My Computer in the properties, I have more than 2 gigs of space left on my flash card. Is the only solution to reformat the card and retransfer? Do I need to not delete files after I have read them? Betty Nobel
