Hello Everyone, I have tried a different card, The original one that came with book port. I reset the machine, and reformatted the card. Still the transfer starts, but does not complete. The scale usually plays through 3 times. The second time I hear the scale it is fast. Then the book port announces the title of the book. When I unplug the USb cable I do not hear the usual buzzing sound. I just hear the chime that let's me know I've disconnected something. Any suggestions would be very helpful. thank you Nancy
