Sujet : Help With PSN Credit Card Information

So I saw that there was some sort of Easter Sale on PSN yesterday, I bought The Walking Dead, downloaded it and then decided to buy LBP Karting since it was relatively cheap and it was a game I had interest in for quite some time, but when I bought the game it said that my credit card information was invalid, even though I used it earlier to buy The Walking Dead.
Anyone here who can help?

You got this message after the transaction?

No. It doesn't let me add any funds without the correct credit card information (even though it is correct).

Maybe you can find something here?
