My itunes store app will not open since the ios7 update. Anyone experiencing this?

When I tap on the Itunes store icon it opens to a white screen but never connects. And now I'm getting a itunes update that asks to me to agree to the terms and conditions but it won't let me agree or send to my email to accept it there................. Now all my apps wont update until I agree to something it won't let me agree to. Help!!
