Pokemon Platinum - about saving

Hi there!I have put Pokémon Platinum just yesterday on my Supercard. awkwardly, I can't save. >_> It just doesn't work. For example, saving takes less than a second - and each time I want to load the game, it starts a new one instead. Can anyone help me please?

save twice in the same place before yu shut off your game. thats what i have to do .

Well. I did do that, but oddly it didn't help. I even saved thrice, but...

hmm no idea then sorry =/

try downloading it from a different website thats what someone did i think and it worked

Well, I downloaded it from... Four different sites. It didn't work. >_>
