App dosent work

I open the app and a msg come up saying "An update for mtv Al Lubnaniya is available on AppStore. You cannot use the different sections of the app unless upgrading" and you click yes to upgrade nothing happens. I event uninstalled it and reinstalled it yet nothing changed. Oh well...if you know of a fix please let me know. by the way I did update on the Appstore and you can guess the resluts.
