Greatest Journal lost a number of icons recently, and so I had to upload the icons again, and thus the links changed. You can see the whole corrected set here.

I know that it would be a pain, but you should think seriously about copying all the icons to your own image hosting service (you have my permission to do this) and uploading them to the custom mood administrator yourself. That way, you have control: you wouldn't be stuck without your mood editor if, for some reason in the future I make changes, leave Greatest Journal, whatever.
