I have tried to access my iTunes tonight and I get a box that says - The file "iTunes Library.itl" cannon be read because it was created by a newer version of iTunes. That`s all that about? I did system restore a few days ago, but my iTunes was still accessible. What`s caused this?
It seems like you restored an older version of iTunes, than the one you were using before the restore. Download and install the latest iTunes version and retry opening your music library
