After uninstalling the Blackberry Report Pack from MessageStats you will notice errors in the Event Log stating that the Blackberry Report Pack License has expired even though you have already uninstalled it.
The uninstallation does not remove any license information, this is by design to prevent having to reinstall the license every time you upgrade to a newer version.
To remove the Blackberry Report pack license information from the database run the following SQL Query on the MessageStats Database server.
Delete from [MessageStats].[dbo].[T_LicenseData] where ID = 'BlackBerryReportPack'
Enhancement request TFS00042189 has been submitted to Development for consideration in a future release of MessageStats.
