I upgraded from html Editor 3.0 to 3.5 to fix the IE11 problem. It works fine in Firefox and Chrome - but in IE11 I just see a gray rectangle with no icons. I think I have uploaded all the relevant css and script files bit I am stuck. Look at www.ctcchicago.org/aatest1.asp to see a test page

Ron,

You still have old jquery version included on your page. Just delete ScriptLibrary/jquery-Latest.pack.js and reapply the editor.
