SAP WEBIDE not able to run the application. Run button is disabled

Hello,

I am developing an UI5 application using WEBIDE of HANA cloud platform. I created a basic application and ran it and later also deployed it on to the Hana cloud platform. After that the 'Run' button and the 'Run' menu of my WEBIDE became disabled. Not sure what am I missing here?

Regards,
