Go here... https://www.blackberry.com/CSOHelp/index.do?ft=generic ...and fill out the form. Use, in the "Please select a component:" field, the AppWorld Billing/Payment selection. Any other selection will simply route you back anonymously to the BlackBerry public forums. Be sure to also include the reason why you have exceeded your maximum allowable PIN associations to AppWorld (e.g., multiple RMA, warranty replacement, etc.). If you don't have an "Order Number" for that field, just use anything (e.g., "123456").
