I lent my computer for someone to use over the week and I find out today that they renamed the Icon in the finder that is a little home (not sure what it's called). Now my whole iTune and iPhoto library (and i suspect the rest of iLIfe) has been erased. Although, I can still see the files on my computer, they will not appear in either of my programs. I can try the "Add to library" option but the files never show up when the pop up menu comes out. Someone please help. What do I have to do to restore my libraries? Thanks
