Rebuilding database with new bookid

[bendrew]

I'm using v5.41.04 and my real intention is to let hoster rebuild the songs database assigning new available lower nos. I don't know if this is a good idea to uninstall and re-install hoster,then rebuild the database when hoster open. Just a suggestion if it will do it. I can use songverter to convert the song to a zip file and then start all over with hoster but this will be a painstaking job for 120,000 songs..
