I believe you are using Mozilla firefox, If you are using the Mozilla please ensure you enable the JAVA plugin by going to Firefox > Tools > Addon > Enable Java(TM) Platform SE 625.
Please also try using Internet Explorer and let us know if this works for you.
I have cross checked. There is JDK 184.108.40.206 I showing. Enable Java(TM) Platform SE 625 is not there.Internet Explorer also not working.
Pls help me
I have cross checked. There is JDK 220.127.116.11 I showing.
This means you have installed JDK 7 Update 25. Ensure you uninstall Java 7 and install JRE 6 Update * release. Hopefully this should give you the plugin in Mozilla. And then check with other browsers as well.
