I have two news for you, one good and one bad.
The good.
After installing the path, to have the replay and need to add a command called in the game.
The bad.
Le put it in some forum do not know what. I do not use replay (for me the biggest weakness of the game), do not worry and write the address. Replay for me should be iguar Microspose of the GP4.
I think I saw on the website of Codemaster. Give a search there.
Post here if I find the link.
