Subscribe2 404 errors

Hi

I am using subscribe2 successfully within my blog.

Having moved my wordpress install within the server, I installed the redirection plugin to manage any 404s and 301s.

I have noticed that I get a 404 registered from the subscribe2 plugin in the admin section when writing or editing posts.

The error generated calls for:

​/wp-content​/plugins​/subscribe2​/tinymce​/langs​/en.js

In the tinymce/langs/ folder is only 2 js files en_us and nl_nl

Is there somewhere in the plugin I can change to call the right js file (i.e. en_us.js instaed of en.js) or is there another workaround?

Thanks in advance
