I get the following error, on my desktop computer, when I print a report. However such error does not show after I build an application or on another computers. The error still shows after I replace the files ReportBuilder.app, ReportOutput.app and ReportPreview.app from an computer without error. Can anyone tell me how to solve the problem?
