If Java is not working (this is specifically due to an update to Java 7 but may fix future problems too)

1) first uninstall Java from Control Panel - Uninstall Programs

2) Then Install JavaRa (this will remove traces of Java from previous installs that could conflict with a future install)

3) Run JavaRa and do the following

	1. Remove Older Versions
	2. Additional Tasks

		One check box at a time go top down and do them all, with the exception of the two Logfile ones and removing JavaRa Language Preferences which are not necessary

4) Install jdk-6u38-windows-i586

5) Make sure the new install of Java's add-on is not disabled by Mozilla automatically due to it being old and having a security problem.  Go to Tools Add-ons and scroll down and make sure it is "enabled".  If you use another browser check the same thing there.
