Not able to start LOADUI

Hi,
I've tried all steps listed in this thread. I've uninstalled java old versions, downloaded and installed Java 7 (build 1.7.0_03-b05). I've run javaws - uninstall and javaws - clearcache steps from commandline. I've removed the certificates from java console/ deleted all temp files and have also unchecked the "Enable online certificate validation". After doing all that, I've reinstalled loadUI but I'm still not able to launch loadUI 2.0

The error I'm getting is -

"Unable to launch the application."

On clicking Details I get -

"Error: JAR resources in JNLP file are not signed by same certificate"

Below that I have 3 tabs -
"Launch file" tab says -
