Small issue with updating to AKAIO 1.7.1 on my Acekard 2i

Hi gaiez ;DOk, so last night I downloaded the file for AKAIO 1.7.1. I backed up and deleted the already-existing "__aio" folder that was on my SD card (AKAIO 1.7 files), and replaced it with the "__aio" folder that was in the AKAIO 1.7.1 file. I mean, that's pretty much all there is to updating it, right?So then I played a game. That's when my Acekard 2i started throwing a tantrum, refusing to play any of my saved files, insisting on overwriting them with a brand new empty save. Indeed, when I hooked up my SD card to my computer and looked for the "GAME.NDS.SAV" file that belonged to the game I tried out, I found two for the same game.I deleted the newer "GAME.NDS.SAV" file and completely got rid of the "___aio" folder that I downloaded with the AKAIO 1.7.1 files. I then reinstated the old "___aio" folder (the one that came with the original AKAIO 1.7 files) back to its original place on my SD card, so effectively it was as if I had never upgraded AKAIO to 1.7.1. And then my saves began working again.I can hear you asking: "so what's wrong"?I just need some incredibly detailed instructions (things go wrong without detail) on how to upgrade AKAIO from 1.7 to 1.7.1 without having my Acekard 2i overwrite my saves.Much obliged, folks :)

Replace both _aio folder and akmenu4.nds, they seem the same but they were both updated, you might want to update the loaders as well while you are at it.
