Hi, We once had a discussion about Audible.com sometimes not showing format 4. I am having this problem now. I remember the discussion but not the solution. Does anybody know how to resolve this? I downloaded one part of a book in format 4 and went back for part 2 and the highest format that is showing is 3. I know that this is an audible problem because the first part of the book is now not showing format 4 even though I downloaded it in format 4 earlier today. This is too strange. Robert Carter
