Regarding Inserting Demo

Sir,
I have purchased the TravelWP theme from themeforest.net. As I have no knowledge of coding so I purchased this theme to create and publish my website through wordpress. I was all inserting demos of the theme, and it created multiple menus (e.g. page is filled with these menus). Eventually, I trashed all the pages. Now my website page is showing page is not found, and it is filled with menus. My website is yoursholiday.com

Please help me, as I want to create my website using the demo theme of TravelWP. Help me how to get rids of these multiple menus, and display create all the pages of demo please.
