Translate specific text

First of all, sorry for my english. I have a doubt with that theme. I have the spanish version but i have found little text in english and i don’t know how to translate it. I have downloaded Poedit, edited .po archive and uploaded .mo archive to my web by ftp, but I don’t have any results. What can I do? I don’t know where is the mistake.

Thank you so much!! And congratulations for that wonderful theme.
