[Plugin: BuddyPress Photos tags] Translation PO file

BuddyPress 1.5.4

I see that in the language folder there are some PO and MO translation. I need to use the es_ES translation that is there, but it does not activate.

The file is:

bp-album-es_ES.mo

Note it sais “album”, do I need to change the name of the files??

Thx, Donald.
