[Plugin: BuddyPress Activity Plus] Localization

I am trying to translate this plugin to spanish, I used the po file on languajes and from than made a new ona named es_ES edited on poedit uploaded it but is not working, every other plugin works ok, am I missing something?

You must generate the “.mo” file and the filename must be “bpfb-es_ES.mo” to work fine!

Spanish: Debes generar el archivo “.mo” y el nombre del archivo debe ser “bpfb-es_ES.mo” para que trabaje correctamente!
