Installation

Download the *.zip file to your hard drive.
Extract the files to the same folder on your computer. There are several free utilities to help you do this. One can be found here.
Click on the appropriate *.html file to run applet. You should see a box in the center of the applet. Applet should load in a few seconds.
If the applet does not load, there's a good chance you need to install the appropriate java run-time environment (JRE). Click on JRE link on navigation bar at the top of this page for more info.
After installing the JRE, click "refresh" on your browser and applet should work properly.
If this doesn't work, you may need to do a clean install of the JRE. In Windows, go to Start/Control Panel. Click on Add/Remove programs. Scroll through the list and remove any programs with "java" in the title.
Install the JRE again.
If this does not work, contact your system administrator.
