R4 help

I have R4 card for Nintendo DS, I am using this card since long time working fine with downloaded games, I recently downloaded few new games and they are not playing. I am getting the message "The save date could not be accessed. Please turn the power off and reinsert the DS card". The .SAV file is there in the card. I need your help in this regard.Thanks

You have got to check and be 100% sure they are in the R4 folders or it will not work, make sure you have the latest firmware too which is 1.18 if not download it off the R4 web.
