Somehow some sample reports from a later version of Adagio Ledger have been installed on your machine. You will be unable to open those reports with the version you are running (which is quite old). There have been many, many improvements to the Financial Reporter since V6.8A - it is well worth the price of the upgrade.

What are the names of the specifications you are trying to open? I will see whether we have earlier versions of them I can e-mail you.
