problems with Skate It DS

??? I've been having a problem getting Skate It to run on my DS Top Toy, every time I load it , it says something like sav file coud not be found.....ironically when I look at the data on the card on my computer it shows a bunch of Skate It sav files. Any clue as to what I'm supposed to do to get it working?

Save file error is in the game itself? The save .sav files must be named exactly as the ROM's filename.
