Ds save data problem

I downloaded the flips several times but everytime I open them they all say the same thing "the save data could not be accessed.Please turn the power off and reinsert the DS card", which I did reinserted several times too. Same thing happens in disgaea when I try to save for the first time. I thought maybe it's cause they are european releases but I tried the american one too in Disgaea and I get the same problem.Is there something I can do so I can fix it?
The japanese releases play alright.

This issue is covered in the Common Issues thread.
