Ron,
Is the app called Soldatini International? If so, please download the app.
If not I really don't know what to say, the app is in the app store, I just checked, you should have the app already installed on your tablet, because you did download the app before.
Let's try this one, you should have the app in your "purchased" app, if you open the App Store you need to click on the second icon from the right at the bottom of the page.
Once there, search by writing in the box at top left corner for Soldatini International and you should find the app, then just click on the little cloud to download it.
Your issue is not related with the magazine or with the app, seems related with your hardware/apple account.
If all of this doesn't work, I have to ask you to go to your local store and ask them to help you with the app store.
