[Plugin: Social] Cannot get .po-file to work

I’m having problems creating a .po-file which will work with this plugin.

Is there an official .pot file I could download to translate? Or any tips on what I’m doing wrong when I try to generate the file?

I’m using PoEdit to create the file from a catalogue.
