I tried to purchase Pacemaker today and i get the message "There is a problem with your credit card authorization. Please try again or visit blackberry.com/appworld/support for more information. (Error ID: 10000)" i've read all the past forums including RIM's article about it
then i tried paypal and then i get that there is no credit card on file. add a credit card or paypal balance.. i do have a card on file.. this is getting really annoying
