You'll have to do the same for your movie path.
1) New string value called "MoviePath".
2) Double click on it and put in the path to where your FFVII movies are. For example mine is "C:\Program Files (x86)\Square Soft, Inc\Final Fantasy VII\data\Movies\".
If you have any more problems it would proably be better to just re-install the game.
Anyway, glad I could help
