Gaming NFS: Nitro refuses to work for me!

[Argonitious]

I'm having a strange problem with Need For Speed: Nitro (also called Need For Speed: Montreal). It used to work on my Wii, but now it doesn't! Now it gets stuck at the loading screen. Since it was working, I've changed a few things. Even after using the disc's update function, which detected all of my homebrew cIOS stuff, it still doesn't work!

Edit: The save was corrupted, which is why the game didn't work. Everything is fine now I deleted the save.
