Hello and welcome, Pilotbob!
The All4 app isn't available at the moment, we're working with the app provider to bring this to our mutual customers as quickly as we can!
It does look like your software is a little outdated - the latest version available on our website is: 1154.0. You can check for this update on your TV by going to: Settings > Support > Software Update > Update Now. Or, the update file can be downloaded from our website here.
Installing the latest update will help keep the TVs apps and features running more smoothly.
We hope this helps!
