I had this same problem. I'm from Spain, and in the javascript console i saw that there was a problem trying to load the es.js file.
In the coach/includes/ckeditor/lang there is only en.js
Solution:
Go to http://ckeditor.com/download and download the last version of CKDownload.
Copy the lang/ directory to your coach/includes/ckeditor/lang folder. You can also upload(ftp)/copy(local) only your language (i.e. de.js or es.js) but it's better to have them all, as to avoid future problems with your clients.
Note to Couch Crew: include all languages for ckeditor on the couch download, please.
