Okay so last week my brother switched our 3ds sd cards because he wanted to play a game I had -___- I was like what the hell are you doing? So I got my card back and whatevs, you know got mad at him. the whole shebang. Anyways when I went to go look in the mii plaza at the beggining it sais "Could not acccess SD card during last spotpass... something, please make sure the sd card isnt full or right protected.." its not... is this a substantial problem? what can I do?
