I downloaded akAIO 1.7.1 from FileTrip, extracted it with winRAR, put the _aio and akmenu4.nds files on the root of my micro SD, safely remove the SD card, put in my DSi, load it, and I get "System File is missing". I even went back to 1.6, but I got the same error now. Any help? Also, if you're using 1.7.1 and it's working, please upload it to megaupload.com and link me it? I doubt it, but the one on filetrip might be the problem. Edited: Tried 1.5.1, got "Loading" indefinitely. It's not my Acekard or micro SD either. Please help.
