I've downloaded Assassin's Creed Revelations yesterday. I have slim ps3 3.55 kmeaw cfw, and i use multiman (latest version). But when i tried to open game it says need to upgrade 3.72 fw. Then i tried to open game with select + x at multiman, and game opened. It installed game data, but at the end of installing i got an error "Registration of the trophy information could not be completed. The game will quit. (8002291B)"
What the heck is that I searched but couldn't find result for this error. What should i do ?
