Creating reports and dashboards | Stimulsoft community forum

When I try to preview a report from the report designer, it always shows the Exception Report
Object reference not set to an instance of an object.

at Stimulsoft.Report.Dictionary.StiDataSource.SetSort(Object[,,] conditions, String[] sortColumns, StiComponent component, StiDataBand databand, StiComponentsCollection groupHeaders)
at Stimulsoft.Report.Dictionary.StiVirtualSource.ConnectToData()
at Stimulsoft.Report.Dictionary.StiDictionary.ConnectVirtualDataSources()
at Stimulsoft.Report.Engine.StiRenderProviderV2.ConnectToData(StiReport report)
at Stimulsoft.Report.Engine.StiRenderProviderV2.Render(StiReport report, StiRenderState state)
at Stimulsoft.Report.Engine.StiReportV2Builder.RenderSingleReport(StiReport masterReport, StiRenderState renderState)
at Stimulsoft.Report.StiReport.RenderReport(StiRenderState renderState)
at Stimulsoft.Report.StiReport.Render(StiRenderState renderState, StiGuiMode guiMode)
at Stimulsoft.Report.Design.Controls.StiDesignerPreviewControl.btRefresh_Click(Object sender, EventArgs e)

Is there something I am doing wrong?

Windows 7 64-bit, Stimulsoft Reports Ultimate ... I just double click on an .MRT file on my desktop.
