Maybe you could try downloading any app on your computer and then sync it to the iPad. Any free app will do. If you try this, I would sync it to the iPad by using the cable and not wirelessly. I know that sometimes downloading an app can reset things, but you can't open the App Store on the iPad and that is why I'm suggesting doing it on the computer and then sync it.
The other thing that you could try is to tap on either icon to launch the app, and if it appears to open but not load anything, tap the home button and go back to the home screen, then double tap the home button to get to the task bar and then tap on the icon in the task bar and see if the content loads.
Another thought, tap on all of the tabs at the bottom of the apps and see if you can get the content to load that way.
