Apple ID in iTunes Store is keeping me from using the App Store?

I just got a brand new iPad today, and maybe this is because it's my first one and I don't know how to set it up properly, but whenever I attempt to download an app using the app store it says "This Apple ID has not yet been used in the iTunes Store." It is followed by a small text reading "Tap review to sign in, then review your account information. (Cancel/Review)" If I press cancel it won't install the app, and if I try again it just reopens the text. If I select review it tells me to enter my Apple ID password to "create an iTunes Store account from your existing Apple ID. (Cancel/Sign In)" If I cancel, it once again doesn't install the app, and if I enter my password and press sign in, it takes me to a blank pop up which exits out of itself, and then it just gives me the "Tap review to sign in, then review your account information. (Cancel/Review)" again! I'm completely stuck in a loop, and I can't download any apps at all. Does anyone have suggestions?
