the brushes are there, just not an .abr it's in a jpeg format, she's shown the settings and the brush she's used there are 2 jpegs showing two brushes, i'm on a mac so i've taken a screenshot for you. You can copy the settings and make the brush from there. Well the one's that are shown, i don't know the settings inside each individual option.
