Akmenu Not Detected

So i just got a new 4 gb sandisc micro sd and have switched my firmware onto it and when i try loading the acekard it says akmenu4.nds not found. Would this be a problem with my micro sd size or would it be something else? I also have checked and i have the akmenu on my sd card

try formatting your micro sd card. Try downloading the newest version of Akaio and just drag and drop the _aio folder and the akmenu4.nds onto the root of your SD card, don't put them inside any new folders.

Thanks I just fixed it i just needed to download akaio 1.8.5a and put in the new loaders and akmenu
