******************************

When you next go into computer chess, look on the bottom right corner of your monitor. Can you click on the java icon then Open Control Panel.

Once this is open, use the bottom box where it says 'Settings'  - when that new box opens, click where it says 'delete files'.
Then OK

Once you've done this, refresh the page.

Sometimes the java icon is turned off from appearing in the tray.  If you're running windows....

start button/control panel/java/advanced/miscellaneous/check box "Place icon in system tray"

Also try clearing your cache, and even your java cache. see: http://www.java.com/en/download/help/plugin_cache.xml

Still no luck - followed all of your instructions
