Lost all my data due to a page title change, Help?!

Hi, I have a page that includes an external data source, and when I changed the title to the page it disappeared. Does anyone know if theere’s a way to revert back to an older version of the website in wordpress, or potentially how to fix such a problem?

The application is a Google Maps rendering from Google Fusion Tables, and I guess it’s connected to the page title somehow. I did not do this, I’m a total beginner. But was masterful in breaking it.

Help is deeply appreciated, thank you!
