I have not seen answers to your questions so this might be a repeat of solutions but here goe's anyway.
Make sure that you are NOT connecting thru a hub.(a device that multiplys USB connections).
Be sure to disconnect the card reader before removing program. This will clear completely the software from your computer.
Make sure your hard drive has at least 30MB free disk space. Do not use a cable extender for the reader (It will not work)
Make sure that you disable anti-virus program and any other programs that are running. They will interfere with the downloading of Jukebox.
I hope you will be able to install now without a problem.
Good Luck, Lloyd
