Broken

Ive never used this app before today. I wanted to watch showtime and downloaded it and opened and a message says the app is out of date and needs an update, OK,App store says this is the latest version. Ive closed all apps, restarted and tried again. Says an update is required and app stores says its the latest version. Whats up?
