Since I loaded version 4 of Appworld (upgraded to 22.214.171.124) last week, I get error 11000 when using Visa credit card as payment option. I tried creating paypal account, linked to my visa card, but still getting the same error. I have been able to buy from Appworld before the upgrade. Am in South Africa, and using BB Bold 9790 OS 7.1.0 Build 39. Any help will be appreciated.
