reCaptcha Language support not working

[GoogleCodeExporter]

What steps will reproduce the problem?
I am trying to implement the reCaptcha v1.0.5.0 asp.net plugin with the Spanish 
language.
If I set the Language to "es" and try it out, there is no difference
in the text displayed, i.e. "Type the two words", "Get a new
challenge", etc. all show up in English. The same happens regardless
of the language I set for the plug-in, i.e. "ru", "fr", etc.

I can see the below in the script that was generated, however the
display shows up in English. Is there something else I need to do for
the correct language to be displayed?

 var RecaptchaOptions = {
 theme : '',
 lang : 'es',
 tabindex : 0
 };

What is the expected output? What do you see instead?
