Have you started a new-game Plus with that career? That would prevent it from loading that character, as it's not a Final save.
As he says, you use the launcher, from what instructions i read on the site with all the Saved games for those you can't stomach playing ME for the 10 gillionth time. lol
It gave me great instructions, but the one above says what you got to do, but when you do point it into the direction of your ME saved games, make sure to save the config, like as if you altered the games' graphics there.
