When you changed the database location in Crystal Reports, did you use 'Set Location' or 'Verify Database'? The correct procedure when reporting from Adagio data is to use Verify Database. You would need to ensure that the report can be printed or previewed from the report designer before attempting to print the report from within Adagio and the Custom Reports menu.

Something else to note - if you add a 'Crystal Reports 8.x' feature to the report (even inadvertantly), this could cause the report to not work when printing from the Custom Reports menu, but it does work from within the report designer.
