Okay, so I used Gecko cheat codes to hack my Animal Crossing game, and my cousins wanted me to hack their Wii too. So I went over to their house, and setup their SD card to install the homebrew channel. Everthing was setup correctly. When I clicked the SD card menu, the screen went black and said "Error #0004: System data is corrupted." LUCKILY none of their memory was corrupted and all I had to do was reset the Wii. Anyways, how do I fix this error? What's the problem?
