Kingdom Hearts 358/2 Days problem, help please?

Hi!
I am having some problems with my game.
I have a NDS Slim and Acekard2 Flash card with a 8Gigabyte memorycard with the game in.The Problem: After i watch the intro, the game freezes.
I have restarted the game several times, but it still freezes.
What should i do to make it work?
