Save Data could not be accessed

I've downloaded a number of games that give the same or similar message "the save data could not be accessed. Please turn off and reinsert the DS card"
Do I need to find fixes for each individual game or is there a generic solution. If I need to find individual fixes where do I go to find them?
I'm trying to play the games on a DS.
Any help would be greatly appreciated (especially by my grand-kids!)

Wrong board. Please read the Common Issues topic on how to update your flashcart's firmware :)Common Issues

Thanks, I promise to learn by experience :)
