I have half solved this problem by copying all the language files back to the lang/ directory. I had deleted them all except en-uk.js to make it smaller.
As soon as I copied the language files in, the editor worked again. I deleted them to test it... and it still works, even after a browser restart and Ctrl+F5 ?
Maybe something was cached somewhere to do with my old directory structure, or an older version of FCKeditor.
