Please insure that you keep the "bug report" on your desktop. We will submit a bug report to Java after we do the following:
Go to your Control Panel and open "Add and Remove Programs" and Please tell us what version of the Java Application you have. The latest version of the application for win xp home/pro is presently "Version 6 Update16"
If you have a Version which is older than that you should remove/delete that older version from "Add and Remove Programs" and install the latest version by going here: http://www.java.com/en/download/manual.jsp
It is normally acceptable to load newer versions of Java on top of older versions but in this case we want to start fresh with a full latest version.
Scroll down a bit to the "Windows Download section" and download/install "Windows XP/Vista/2000/2003/2008 Online" This is a 10MB download.
After downloading/installing this latest version; close all windows and applications which may be running and "restart" your confuser.
Then click on the link once again to go back to the download page and select the link which reads "Verify Java has been Installed Correctly" If the application has downloaded/installed correctly then this test will advise you that Java is working correctly.
Then; Please let us know the results and we will see if we need to go further.
