Is it just your data pack that needs updating?
The version of the game should be 1.0.1 (downloadable as soon as you start the game, via PS3) and the datapack 2.0 (via Menu>Information)
Take a look on this: Information
But...if you still want to have the Patch then follow this One, thou try the official one.
The Datapack should be inside the game.
If you have your PS3 with internet, you shouldn´t be doing all of this...
