I have purchased lots of apps before via my phone. I am trying to buy swiftkey new edition. when i hit purchase, it shows me my credit card, but says unavailable. I try to add it back, the CIV number changed since the last buy, (but hard to believe that is why its says unavailable), but it just cycles and won't go thru! Is there a way to do this with a real computer? It is very painful trying to re enter again and again on little touchscreen. Thanks.
