Regen hair pack

I have extracted the file to the 'hair' file in 'facegen' and reloaded the skin, but when I start a new game without real players to check if it works, the hair is still the same, and the players have no bodies. Does anyone know what I need to do to get it working, Thanks

Are you sure you placed the file in the right place?

Well yh, its with the other hairstyles?
