As of the Campaign Manager 2.3 release in August of 2012, a new Reconciliation Report replaced the original Recon Report with enhanced functionality.  The old Recon Report has been archived for legacy use in the Advanced section of the Client Console.  To access it, simply click the Advanced link at the top of the screen and then click the Legacy Reconciliation Report link.  All of the old functions and features have been preserved as is should any user need or want to use the original report.

Note: the Legacy Reconciliation Report option will be removed in an upcoming release of Campaign Manager.
