Just restored my ipad, Office2 HD no longer exists and I've lost all my work - how can I get it back???

Don't you have a backup on your computer or iCloud?

You can redownload the app at no charge.

Hopefully, if you reinstall the app, your documents will reappear.

If they don't, these links may help
