    Firstly apologies if this is not quite the right place but I'm pulling my hair out trying to sort this out.

    Stupidly upgraded from 11 to 10.7 and now need to revert back, followed this tutorial iTunes: An unknown error occurred -42408 - MacRumors Forums however when I get to using Pacifist I get two errors
    DiskArbitration error 0xf8da0002
    which I can then continue past but get another toward the end
    The file “CodeResources” couldn’t be opened because there is no such file.
    Google is not my friend today so can't find the solution, any help most appreciated.

    Delete everything what has to do with iTunes, and than install a fresh version
