Not sure what happened, but suddenly I can't use youtube anymore. I pick the app and it always says "ready to install' I selects it, and it install up to 100% in the blink of an eye, because technically I already have it. I can't launch the app for use, just install. If the dang xbox had a file manager I'd just uninstall the whole thing and reinstall, since it probably got corrupted somehow, but I can't. So its now useless. anyone have any tips or something?
