R4: Data access problem [/resolved]

I've been having this problem for a while with my R4.
Every time I get a game and load it into my card, I open it up and it says that I can't access the saved data.
I thought that it was the file that I downloaded because some games work and some don't.
Is there a way to fix it?
I have an R4 microSD, can someone help me please? :3

Edit: Nevermind I saw a topic that was the same and looked through it.
