I read topics describing the same issue, but having formatted sysnand instead. They appareantly needed to log back into nnid on their sysnand. My emunand was the one that was formatted so how do I log back in? When I hit "Nintendo Network ID Settings" on sysnand it brings up the error. However when I do it on emunand it bring me to some setup thing with asking the child to give the 3ds to their parents. I'm afraid to go on however because I don't want to accidentally create a new nnid for my system. I also don't remember the username or password if those exist? Do they exist? I think I could guess them. Do I just keep going forward on the setup thing or should I contact nintendos services?
