Getting started: MAGIX Photo Story

I have just added to a new slideshow with 168 pictures and titles with relative ease. The problem that I have now is editing these pictures. I have successfully edited the picture I have in the system and have reviewed the slideshow and it looks perfect.......................................Burning this show reverts back to the original project!! It is nervewracking to burn many DVD's to have the same original without the changes on the same disc. CANNOT GET ANY ANSWERS TO MY QUESTION!!!!!! DRIVING ME CRAZY...................
