Thanks. Tried updating my security number without success. It seems a second complication is that I am currently resident in Norway with a UK credit card registered in the UK App Store. It seems the UK App Store refuses to accept the billing address post code (zip code) for my credit card as it is not a recognized UK code. This was not a problem before the upgrade to iOS 7. Both my old iPad and iPad mini worked fine before and I have a couple of hundred apps on them. Now neither will allow me to download new apps, though I am able to update current ones. I have also recently purchased a new iPad and I find it won't display already purchased apps. However, I can download many of my already purchased apps directly from the App Store, but by no means everyone. And I am unable to download any Apps not previously purchased.
I don't want to change to the Norwegian store, both because of the incompatibility of apps in different countries and for linguistic reasons, not to mention the need to change them again in a couple of years time. Is there a simple way to get around this computer inflexibility? would be grateful for all good suggestions!
