Was working well, now has issues

Ive been using it to research hotels around the world (event planning) and it seemed to work well but just today it stopped working. When I open it I get a "data corrupted" error message and now Im unable to use it (I closed it out and restarted the app a few times but no luck). Id be more than happy to update my review once the issue is fixed. As I said, it was working well but now its not working.
