License verification issue

Hello, 
upgraded from free to pro addition today. When I attempt to open the app the following message appears - License verification "This application is not licensed. Please purchase it from Android Market". The app was purchased from the Android Market will not open. Installed on Motorola Droid original, non-rooted Android OS 2.2.2 Paid through Google Checkout. I have uninstalled free addition and pro addition and reinstalled pro without success. Very frustrated any help will be greatly appreciated.
Thanks,
Doc
