Hello and sorry for revive an old post, but is one of the first search results in Google about this topic. I have the same problem after returning yesterday to the modding community since 2013, and when i launch the CK it crashes with this "new" problem i haven't seen before, i fixed this by just changing one line. In the SkyrimEditor.ini file i change this:
[General]
sLanguage=ENGLISHTo this:
[General]
sLanguage=SPANISHAnd that's it, problem solved, just change the languaje of CK to the languaje you are using in your game, and of course if your CK installation is fresh, just add the line. Kudos to Grospolina for the orientation.
