Ok, that helps a bit. Office 2000 has nothing to do with it though, unless you meant Windows 2000.
Win 2000 shouldn't make any difference.
All the smileys are showing up just fine for me. It must be a setting on your system that is blocking the download. Are you running any kind of virus software and anti-spyware? That could be blocking some things.
There are also some setting in Internet Explorer that you can change. Open up IE, it doesn't matter what web site. On the menu bar select "Tools" then "Internet Options". A small window will open up with a bunch of tabs on it, select the second tab which is labeled "Security". About mid page you should see a virtacle slider that should be set about mid way. If it's not, you should move it there. Save your setting by clicking on "OK" and try the forum again.
