In Need of DS-X Help

Ok, so i bought the DS-Xtreme and some games work fine, but some of the others go to a screen that says "Save Data Could Not Be Accessed, Turn Off The DS and Reinsert the DS Card". How do i fix that?

I already tried clearing both the .nds and the .sav files off and re adding the .nds, but it still does it.

Have you tried changing the savefile type? Normally, the setting should be set to "Auto", but maybe yours isn't or doesn't have that capability.

how would you do that?

I checked the Common Issues Thread, but it doesn't make sense. I updated the DS-X to the latest version but it doesn't work still.
