Resetting the DS game "Alexandra Ledermann"

Hello,
to respond to Marc (it might be a bit late, but it could help others)
so first you need to turn on the console after putting the game in (in the small slot located at the back of the console)
when the warning message appears, you need to touch the screen with the stylus located in the slot on the right side of the console, then you should touch the small box named Alexandra Lederman (there's a small image). The game will start and you'll arrive at the menu where there are 2 choices: either RESUME GAME or LOAD GAME. With the stylus, press LOAD GAME. One save will appear directly on the screen. Now press the small icon representing a trash can, which is located at the top right of the screen. If there are several saved games, press the icon again. And there you go, I hope this helps.

Good luck and enjoy the game, I really liked it.
