Renamed /etc folder by accident, fixed etc now icons gone

Making a file repository and instead of clicking new I clicked edit and changed the etc repository. I renamed the repository back to etc and entered the location back in but, now the icons on the repository monitor no longer show up. When I go to the location of where the icons are they are nothing but red x's but I click on them and they show in a new window.

Is this a problem with the mime set up?
