due to me being German but wanting access to the full content of the AppCatalog I've set my TouchPads region to USA - when I tried to buy the KalemSoft Media Player right now it prompted me to enter my CC information, which I did, but it refused to take it and said the CC might be faked. Since it's a german CC I guess that's the reason, now I can't reg it with the AppCatalog.

Is there any kind of workaround to this that doesn't require wiping the device, setting up a new WebOS Account and entering a different region?
