Larry/Rob, While using the Book Port today with a 1GB Kingston CF card, I got the = following error messages: When I pressed the "2" button while listening to a book to pause = text-to-speech, I heard: 'Application file write error' While browsing some MP3's in a sub-directory, I heard: 'FS Memory. Out of DROBJ structures. Error accessing index file. There are = no files.' This error locked up the Book Port, and I had to remove the = batteries to reset the unit. The reset corrected the first error above, but = when I browse the affected MP3 sub-directory, I repeatedly get the same = error message. FWIW, the sub-directory contains 38 MP3s. Peter Peter=
