I'm playing Brain Training on my M3 Simply. It all works fine, except the option to download additional Sudoku puzzles doesn't work. My Wi-Fi definitely *does* work, as I can use the DS Browser, Mario Kart WFC etc. etc. I've also tried taking it to a couple of download stations here in the UK, but I can't get them to work at all! Mind you, I wouldn't be surprised if they were broken anyway. Has anyone had any luck downloading the extra Sudoku from within Brain Training / Brain Age? If so, how did you do it?
