You may receive this error while attempting to link your MyNintendo account to the Wii Store. This comes as a result of non-alphanumeric characters in either your login name or password. To work around this problem, simply remove these characters, apply the changes to your MyNintendo account, and try again. (vie email, thanks Robert)
But i have no idea what else to do.
