Try uninstalling Java and reinstalling it. Go to java.com and click on the blue button there to download and install the latest version. Once it is installed restart your computer.
If you are still having problems after this please make sure your Java plug-ins are activated by going to Tools in Internet Explorer then down to Manage Add-Ons (if there is a sub-menu here please click on Enable or Disable Add-Ons).
Make sure everything published by Sun Microsystems Inc (in the second column) is enabled. There should be 3 or 4 seperate items in the list for this.
Once they are enabled you should have no more problems with the site.
For Firefox, go to Tools and then Add-Ons. Now go to Plugins, and make sure everything that says Java on it, is enabled.
If the Add-Ons are already enabled and you are still having problems, please let me know.

Erwin
