Hi, I've got an MT-Card that I use to play other games on my 3DS, and I recently got a Class 10, grade 1 Micro SD card to play Animal Crossing, and the game worked fine for a few hours. The next time I tried to select the game, it wouldn't display and the 3DS would show 'There is nothing inserted into the Game Card slot' message, even when in MT-Card mode. Could anyone give me some help. Aside from that, the rest of my games work fine, I just can't get Animal Crossing to work! Thank you!
