I can't upgrade from IOS 6.0.1 to IOS 7.1.1 on my iPad 2. iPad says it has downloaded IOS 7.0.3 but cannot verify the installation if I try and install it. It claims that I have lost internet connection, which I have not. I cannot restore or update the iPad in iTunes either, if I try to, I get an error message which says that I 'do not have permission to access the requested resource'. I am using the latest version of iTunes on Windows 8. I have tried putting the iPad in recovery mode and restoring it with iTunes, the result is the same.
