[ROBERT A ROGAN]

Can anyone help me, I installed a CDG onto Hoster and due to time did not enter Artist`s names, just inserted a ????, intending to insert Artist`s later. When I try to change ???? for the artist`s name and save Database there is no change to my Book Listings. I have even installed the whole CDG Again adding all information,but even when I save on database! no change on my song book. also I have tracks that are out of order,but only on one CDG. Can I delete this CDG and reinstall it on the same book ID.
