Have you tried playing the game, creating the save file, and exiting the game to reload it again?
..or try moving it to sd card, copying/moving, moving it back once you created the save game file?
Skeptical?Everytime I update u on a post, I download ALL of the files I need to help you install, and head straight to my wii to test them... I put my system at risk to help you out, so if I seem unsure, I'll get there... Don't criticize.
