Have just tried to update my apple youview app, but this failed owing to my IPod will only run on IOS5. Instead it gave me the option to re-load the old app, which loaded OK. I then had to synchronise with the Youview box again, which it did OK. But now the app will not open. It opens initially, but then closes immediately. I have tried deleting the app and re-installing, but with same result. Any ideas?
