Hi Joyce,
You don't need to change the title of the save in any way -- that's one good thing about Nancy Drew saves.
-- First, save the file MaG e-mailed to you to your desktop where you can find it easily.
-- Open up your saved game folder, which is in My Documents as a subfolder.
-- Copy & paste OR drag & drop the save file from your desktop into the subfolder along with all your other saves.
-- Exit all folders.
-- Start up the game as usual and load the new save from the in-game load screen. You may need to scroll down a way to find the new save.
