Save data error on startup Acekard2

I'm using a Acekard2 on my DS, and have many games running fine, but when trying to run Monsters vs. Aliens, I get the following error when starting the game;"the save data could not be accessed. please turn off the power and reinsert the DS card".I have tried several different version of the game (US, Europe, etc.) and also tried the arm7 fix to no avail.Can anyone help.... ???

What firmware version do you have installed on your Acekard?

That I'm not sure of.Didn't flash any firmware when I got it, just loaded the __ak2 folder, and the akmenu4.nds file on the sd card, along with a Games folder with the games in it..

Your firmware is probably outdated. Update it to AKAIO 1.5www.linfoxdomain.com/ds should have it.You will also want to use the latest loaders.

OK, thanks.I was using Acekard2 menu v4.18, I'll give the one you linked to (AIO) a go as well as check to see if I have the latest loaders
