Twitter Feed Widget in Bapia Theme

I need guidance on activating the “Bapia – Latest Tweets” widget so that it links to my Twitter account? I’ve tried different ways of inputting my Twitter UserName but nothing seems to work. When I view the website it displays “Twitter feed loading” but nothing happens.

Buy the theme or login fom the account that you purchased it with and ask the author P.s please use one thread for all issues or if clogs up the feeds. Thanks
