Cannot Change Language

I am trying to get started, but cannot change to any other language from English. I am clicking on the Change Language link at the the top left corner of the pages, but nothing happens. Any suggestions?

If you are using IE8, the language switch doesn’t work. You will have to switch to compatibility mode in your browser to make it work. IE8 comes with a compatibility mode button which is up beside the address bar. This makes the browser work like IE7 for our site.
