Buddypress Corporate Theme localization

I've been translating BuddyPress Corporate Theme to spanish, by means of a .PO file which I've generated from the theme files with PoEdit (Windows).

After creating the es_ES.mo file, I've uploaded to the BuddyPress Corporate Theme (in /wp-content/themes/BuddyPress Corporate, but it doesn't work: many character strings are in english, as you can see in http://irati.pnte.cfnavarra.es/redpnte/. Then, I've renamed the file to buddypress-es_ES.mo, but to no avail.

I've tried other locations for the .mo file, but the problem remains.

My installation: WPMU 2.8.4 and BuddyPress 1.0.3. The translations of WPMU and BuddyPress have been provided by BuddyPress-es.com, in http://www.buddypress-es.com/noticias/descargas/

Can you help me?

Thanks in advance,

Eduardo Larequi.
