This does happens occassionally. Not a often, but it happens. You can change the name of your old file or delete it. After doing either one let it sync. First, delete the new sync file upon completion of synchronization. Remove your device for its cradle and go settings to rename the device to your original name. Let it sync again. It should take on the original name again. If you change the name of your file, you can change it back to its original name too.
