How do I resolve the issue when using an XML file source in Crystal Reports?

Question

Electronic accounting

I make a report in Crystal Report, I specified the source as an XML file, I marked everything. I start the form with the CrystalReportsViewer report. But for some reason he asks for a name and password? What is the reason ?

ReportDocument report = new ReportDocument();
report.Load("Reports\\NakladProduct.rpt");
crystalReportsViewer1.ViewerCore.ReportSource = report;
