I'm having problems with ADE. It keeps looking for a library book that I've already returned. I've returned the book, then gone into the My Digital Editions folder, deleted the book itself and the annotation file, but ADE still keeps looking for it when I start the application. What else do I need to delete so that this stops happening? There's obviously still some digital residue somewhere that I'm missing... (This has only happened with this one particular book. I've checked out and returned other library books without this problem.)
