I usually use my iPod to listen to my audible content, but have just gotten a Creative Zen Stone Plus as an extra player. I can transfer my audible files, but while they show up on the screen, they don't play - the player just skips to the next mp3 file in the list. Any ideas what I can do to make them play, short of burning and reripping? According to audible's website, they should transfer fine via iTunes. They transfer, but don't play. Some with folder structures, maybe?
