Dean’s FCKEditor For WordPress

having an issue with the plugin. It was working amazing I loved it but when I went back to use it today it was all messed up. I didnt change any settings or deactivate it sense the last time I used it. But when i went to edit a post the text didnt show up in the post box and there were no controls available which the plugin is supposed to add. Can anyone give me any insight?

best regards
