I have a PSP that is about a year old and it won't update to 4.51 today when I bought a new game, it says there is an error (DADADADA) I believe. Can someone please help me with this? I thought it was the game itself so I took it back to the store and replaced it, it's still doing the same thing. I currently have version 4.40 (I believe). It will play any other game that I have that was purchased last year, but "The Simpsons" won't play on it, which just came out. Any help is appreciated.
