App Store Review Account Info window takes to blank screen in Itunes

I am trying to use App Store on my iPad for the first time. I open App Store, find an app, tap on Get and see the following message:

"This Apple ID has not yet been used in the iTunes Store. Tap Review to sign in, then review your account information"

I tap on Review, and it takes me to iTunes and a blank screen with the windmill ad infinitum.

I have run out of things to try to fix it.
