I overcame this problem with the following steps:
1. Open the original game folder (the older )
2. Access the "www" folder and copy( or cut) the "save" folder
3. Open the new game folder, and then the "www", cuz he will be there for your eyes to look at; the folder you craves so much for~~
4. Replace the current "save" with the older, by pasting what you previously copied( or cutted): Your original game files!
5. You're ready to play, monsieur!
