There is no reason to do a new install because as far as I can see, everything is working fine. If you'd like, try reupload the cgi scripts to see if it helps. Do not reupload the 4 variable files. This is all you would be doing anyways if you were saving posts, settings, and members and then reinstalling anyways. In the meantime hopefully someone else here will take a look at your forum to see if the icons are displaying correctly.
