So I need to update to the newest iTunes after updating my iPod, however whenever I attempt to update to iTunes 8 + Quicktime the update starts but quicky freezes up and an error message pops up telling me that update has an invalid signature and that the computer is removing the update. Is there anything I can do to get this to update? Without the updated iTunes, I can't use my iPod (unless I can uninstall what was updated on it) and I am stuck with the song that are on it?

All help is very much appreciated.

    After followed all this instructions the problem continues the same.
    Honestly, Apple should be doing something, Ipod is an expensive toy and we shouldn't be having any problem
