Activating Magazine theme

Could anyone possible help me, I'm trying to activate the buddy press magazine theme and have been following all instructions but unfortunately the options for me to activate are not there or listed with the themes? It does say when I log in that buddypress is ready to use and to install or activate a buddy press compatible theme only there are none for me to choose from! And it keeps giving me errors when trying to install the child theme. Any help would be greatly appreciated. Thanks!
