If you mean you downloaded the saves but can't use them, that's an RPGMaker thing. Move out the save you downloaded, go into the game, make a save in the slot that corresponds to the save you had before. Then move the downloaded save back in and overwrite it, and when you load it it should be the downloaded save.
RPGMaker has to know there's a save file before it'll check for one, it's a weird system.
