Gaming Problem with Pokémon ORAS

[cris_ne]

Hi!
Yesterday I downloaded Pokémon ORAS, but when I tried to start it I just saw a black screen, not the 3DS logo or the game, just black.
I want to know how can I fix this.
I use a Gateway flashcard with a 16gb micro sd and a 4gb sd.
I tried to change the format (from .3dz to .3ds) but this isn't work
I was playing to another 5 or 6 games with no problems, this thing only happens with this game.
Thanks!!

I fixed it. I just needed an empty micro sd, but I only can have this game. If I put on another one, it hapens the same thing =S
