I'm sorry, I figured it out and I feel quite stupid xD See I lost my game a while ago so I'm using my brother's game and I'm player 2 :P I guess the codes I was using were for player 1 because once I used a codes for player 2 they worked fine, and when I played as my brother's character the codes had worked for him hehe. Sorry I didn't know there were separate codes for the different players :P
