Well, editing the save files is one thing, but first try getting the Silver Trophy again. If not, reload a save from before that quest. I, myself, have no experience with editing save files, but reply back to this if the above doesn't work. (Normally I would say to do a NG+, but the Gold and Silver Trophies, if I remember correctly, can only be obtained once per save file.)
