Help, R4 infinity won't load games

My r4 infinity does pass the loading screen but when I choose any game to start it will freeze without loading the game on my 3ds, I tried formating it but it still has the same problem and patching isn't the solution since it used to load any game correctly but now it just won't, any ideas?

R4 Infinity?
Which one on this website? http://www.r4infinity.com/
