Do you still have the original *.ctz files that have no security settings active? You would need those files if you ever wanted to edit the tunes. If you still ahve them, then using the latest software save them as *.coz files. That will create *.coz files with no security settings. Then when you add the *.coz files to the *.bbx quick setup, you can apply the "Cannot be viewed of Modified" and the "Remote AutoCal" options.
