No addition hidden secrty (Assassin's Creed 3)

Hi folks, I bought a Hidden secrty addition to the game, in yupley it is listed as purchased but in the game nothing from it, no costumes, no weapons no job, I'm already on the 7th Chapter so nothing appeared, I wrote to tech support but still silent. though knowing by experience the same problem in liberase options will reinstall the game reinstall yupley. in short, everything I have made nothing helped. Maybe someone knows how to solve the problem ?

PS When and where it all should appear I know, so do not write look at the estate in the basement or that appears after the 6th Chapter.
