The Java people don't even quite understand this one:http://java.com/en/download/help/error_25099.xml
You can mess around for a long time trying to fix it, or you can fix it for sure.
I would close all browser windows, go to Add or Remove Programs, uninstall Java and reboot.
Then follow the directions in the link to remove any lingering Java folders in C:\PROGRAM FILES.
Using IE or Firefox, download and install the latest new version of Java - Version 6 Update 14.
Check Add or Remove Programs and the Java page (Do I have Java) to be sure the versions are correct, etc.
