Could be an issue with your iTunes account. Do you have an outstanding balances (ie. do you owe Apple any money)? This can happen if you set your payment settings incorrectly. Look at your total balance to see if this is the case (in App store go to "Featured" section at the bottom nav, and scroll all the way down to your Applie ID to see).
