Dynasty Warriors 7 Game save need help

[zzzxxzzz]

when I copy the save game (download online) to my ps3, I got the message saying like " this save game is make by another user. You can't save this game after play ..... If you want to save your game, delete this save game and make one urself" (sorry i can't remember the whole things)

In Dynasty Warriors 7, it doesn't allow save game (download online) to save and play. so I played a little bit of the game by myself and save it

My Ps3 doesn't jailbreak , so I don't know the way to make the save game (download online) to work for my system

In the rar file I put 2 folder, 1 is the save game I download online, 1 is the game I save by myself. Hopefully someone could help me and make the one I download online playable for my system



Any help would be very thankful
