Scott:

-Is this a form or a Crystal report?
-Does the same error occur for all the form/reports in Invoices?
-What about other Adagio modules on this computer - do they have the same error?
-What happens if you Preview the form/report?
-What happens if you Print the form/report to the PDF driver?
-Is this a new workstation?
-If it's an existing workstation, what changed?
-Did you recently install Payables 9.3B?

If the problem is only with Crystal reports, have you tried to re-install Crystal from the System folder?
