No, it is just there are many possible configurations of issues. It will also get very confusing very quickly if we try to help three different people in a single topic in a situation where each person may need customized answers. Typically unless a topic so closely matches your situation that it isn't necessary to actually post anything it is better to start your own topic. In your case in particular you need to do this because all I have seen in posts from you so far in this and other topics is "doesn't work" and nothing about what is happening when you actually try things.
Everybody: If your media files are gone too then the rebuilding library doesn't help much because a library file points to files it needs to play, and those files seem to be missing for some of you. They will have to be restored from a backup you have of your entire computer, re-downloading from the iTunes Store, or from whatever the original source was (e.g., CD).
