Can't Load DS Game...

i downloaded the Gardening Mama (ok don't laugh -_-), opened the rar file, saved the .nds file on my microsd card, inserted into my DS...but when i load the game, it says no .sav file, create one? i poked yes, and then it started loading... then it shows "The save date could not be accessed. Please turn the power off and reinsert the DS card...anyone knows what's wrong? =(
