Hi Sweta,
I am sorry but you have posted your questions to the AEM Enablement forum. In here, we mostly deal with the questions related to AEM Enablement and Training.
That being said, I would suggest you to log a ticket in Adobe Day Care portal. In addition to this, it might be a good idea to include ?debugClientLibs=true URL parameter and check, using Firebug or Chrome Developer Console, if any of the JS or CSS files are throwing an error. Another thing which I can suggest is to try and unbind-bind the HTML Library Manager Configuration in Felix console.This might resolve any issues related to script resolution.
Please try these steps out and log a corresponding ticket in Adobe Daycare.
Thanks
