I friends, i copied this text from a previously unanswered thread.
My Streetpass has an issue where when I start it up it says "Could not access SD Card during the last attempt to use Spotpass. Please check that the SD Card is not full or write-protected." It then proceeds to streetpass normally, however my Puzzleswap game is brought back to where my latest puzzle completed is New Super Mario Bros. Wii. Though I do know that there are newer puzzles because I completed them before this problem began the last one was Pokemon Y. I have tried everything, I turn off spotpass in the options of Mii Plaza and restart the game and it works FINE but after that it returns to being messed up again. I don't have my SD card in the "Lock" position I've already been through the troubleshooting for that and I have plenty of space left on my SD card approximately 197K blocks. I even deleted all of the Mii Plaza's data and redownloaded the updates and my additional streetpass games. If anyone could help me with this problem I'd appreciate it so much, I just want to collect Puzzleswap pieces again.
I am expreriencing exactly the same problem today.
Any help?????!!!!!
