I have had issues with trying to build my database with my F40. The player would find over 6000 entries and would display "building database". However, it would just stay there even after 1 hour . The details on the database would say -1% Progress. I would reboot the player and get a "commit 1/9" on the bootup screen. Any advice on what to do. I have deleted the tcd file which just starts the process all over again. Thanks. Using Oct 8th build.
