Atelier Rorona Plus The Alchemist of Arland [BLES02050]

hi,i don't know if this is the right topic but i'll write it anyway-
i've installed the game and when i run it it works but i get stuck in the screen where it asks me to move the camera in order to make all the white triangles visible (the very first screen when you load the game). I try using my keyboard controlls but they do not seem to work. help me please
