Hi all, I have an interesting problem when trying to send several mp3 files to my unit. I just bought a 1 gb compactflash card to store all of my mp3 files. After sending around 20 or so, when I try to send more of them, the software displays this message, ffmp3: error sending application file. Actually, it's either error sending application file, or error in application file, since my computer here at home does not work with book port, I can't say for sure which one it was, but one of the 2. When this happens, the card has around 800 megs left, so I know that's not the problem. I tried reformatting the card, and the same thing happened. Thinking it was perhaps the file, I reformatted the card again, and tried sending the file that caused the problem, and it sent fine. I then sent several different files, and after about the same amount, the same thing happened. I then tried a 256 meg card I had, and after about 20 files or so, the error happened again, with about 80 megs left on the card. Any thoughts on this one?
