I can't figure out exactly what happened, but I think I opened iTunes from the application folder in the HD instead of in the doc. When I did, all my folders were gone, all my downloads were gone, all my music was gone. I still have the music elsewhere on the computer (I haven't put it all back into iTunes, I think all I would have to do is drag and drop) but I was wondering what had happened. Preferences maybe? Settings or something? Any ideas on how to get my settings back?
