Dear Nayana, try changing or resetting password using the Username. And then try logging in to the official website with the credentials. Then go to 'My Account', click on 'Dashboard' and click on the link available. The code will be generated. This code will also be sent to your Registered Email and Mobile no#. You can complete the final registration from thereon. You might face technical issues. Try clearing the cache, browsing history, restarting the system and relogin. Eventually you will be able to complete the registration process.
