I'm trying to extract my Animal Crossing City Folk save with SaveGame Manager GX, but upon startup of the app, it gets stuck on "Loading cIOS 249". I've tried many versions but I would either get the same message, or get stuck on "Initialize system". I have one version that can get past the loading screen, but only a few of my Wii savegames appear. Even if I try to extract those, I get something like "UID error". Please help!
