App no longer opens on my iPhone 5S.  I can't uninstall it as I am no longer seeing the icon.  App Store says it is installed ... but I am no able to open the app ... it just shows a blank screen the bottom normal seeking alpha icons that are grayed out.  No content, no navigation ... nothing works.  Please help
