Hi, I have no idea if this has happened to you before or not but it just happened to me and I am hoping to God one of you brilliant friendly people can help me. I shut down my mac and when I started it up again all the files I had saved, all my music, all my photo's and numbers and adresses and everything else I have worked on in the last year has just gone. No trace of it. If any of you have any idea how to get it back, I would love to know. Also, all the applications are still there but some of them need to be registered again.
