Me too faced the similar problem. I tried opening in Internet explorer and clicked on Move to Next set of Application Screen, it became green.
You can also try in the same way. Let us see if it works.
I need a help. How can I get the notification when SINP OID or SINP EE will be opened again? Is there any notification option ,when it will open? I missed to submit the application when it opened. Can someone please give me a reply?
