Acekard 2i + DSi ver 1.2A firmware Problems

Hi,
I just got a second hand DSi which turned out to have the 1.2A firmware version on it. I then purchased a new Acekard 2i for it. I thought that because it was not running 1.4 firmware then I should just be able to put the Acekard menu software etc on the SDHC card and it would work with my DSi. I have set up the SDHC card with the latest Acekard software but when I place this in my DSI it comes up with a big red cross on the DSi card slot icon. When I select this icon it says Run “Acekard 2i 1.4 fix on a DS or DS lite”. Having the older firmware on the DSi I thought the Acekard would work without having to do this. What am I doing wrong?

i would do the 1.4 update ......you should use akaio once you get it to work...anyway read this should help http://wiki.gbatemp.net/wiki/AKAIO i will try to help if you run into any trouble .
