language in daily theme [WP + BUDDYPRESS]

Hello

I'm installing daily buddypress theme and saw the main bar already is in english - even my site [wordpress and buddypress ] is in portuguese

* main bar = members, groups, activity etc
** in portuguese [and in default theme of buddypress] = membros, grupos, atividade etc

how I can change this?

Thanks in advance
