The error makes it look like the html editor files aren't being uploaded for some reason.
Make sure you have uploaded the webassist/ckeditor/ folder and all of its contents to your server. I think that might solve the missing editor issue. If you send a url to the page I could investigate more, but that is really what it looks like.
I'm thinking the missing icon images must be a bug. We haven't been able to reproduce it yet. What design are you using? Is the entire icon missing, or is the background color just not set so you can't see it on a white background?
