I've had a A9lh 3ds for a couple months now with no problem and recently I decided to download and install Fire Emblem Awakening and its DLC. The problem is whenever I try to access the Outream gate and the DLC I get a "Could not detect an SD Card. Please download your downloadable maps again." error. I also can't access the official Purchase Maps shop. I tried installing the DLC with both FBI and Devmenu. I have the EU version of the game and DLC but a US 3DS, could that be the problem? I have 2 SD cards and neither of them work.
