I like to take a stroll around my house. I close the 3DS, take a stroll around my house. When I open it up, sometimes games may disappear from the menu, and sometimes an error message comes up. If I do it while a game is open, an error message pops up, and I loose my current state in the game. Whatever the case, I have to restart my 3ds. Sometimes an error message pops up, so I have to turn 3DS off, remove and insert SD card, then turn 3DS back on, and my games appear... until I take a stroll again. Also some applications that use SpotPass say there was an error accessing SD card. Any way to fix all my problems?
