YOU HAVE A Choice of using 4 kinds of Javas 1. the default Java,2. SunJava, 3. unsigned version of the default Java. 4. Microsoft Java. I have also found this problem., it happens after you rebooted your computer after installing 6u1 version of java.
To fix this go to your controll panel>Add or Remove programs then look for java, you should have two different versions there, 5u11 and 6u1 uninstall 6u1 and reboot you computer.
