unable to launch the application

Hi experts,

I have been trying to launch ESR and ID but it is giving me the error:

In chrome  it says

unable to load resource com.sap.xpi.ibdir.client.jar(for ID part)

while in IE,

invalid argument supplied

InvalidArgumentException[ Invalid arguments supplied: { }]

  at com.sun.javaws.Main.continueInSecureThread(Unknown Source)

  at com.sun.javaws.Main.access$000(Unknown Source)

  at com.sun.javaws.Main$1.run(Unknown Source)

  at java.lang.Thread.run(Unknown Source)

pls note that I was able to launch the application earlier buy clearning the java cache. But this time this solution is not becoming fruitfull

I have also changed the java version from 1.7 to 1.6 and have gone through all other links.

Thanks in advance!!
