Reproducing the Issue

Please provide step-by-step instructions on how to reproduce your issue:

if (ExportTypeSelected == "crReportExportFormatText")
#region TXT
{
    // This works do not alter
    // this gets the report name and sets the export name to be the same less the extension
    string outputFileName = "";
    string MyRptName = rpt.FileName.ToString();
    outputFileName = MyRptName.Substring(9, rpt.FileName.Length - 9);
    outputFileName = outputFileName.Substring(0, (outputFileName.Length - 3)) + "txt";
    try
    {
        if (File.Exists(outputFileName))
        {
            File.Delete(outputFileName);
        }

        //CrystalDecisions.ReportAppServer.ReportDefModel. RasRTFExpOpts = new RTFWordExportFormatOptions();
        CrystalDecisions.ReportAppServer.ReportDefModel.TextExportFormatOptions RastxtExpOpts = new TextExportFormatOptions();

        try
        {
            RastxtExpOpts = rptClientDoc.get_SavedExportOptions(CrReportExportFormatEnum.crReportExportFormatText);
        }
        catch (Exception ex)
        {
            btnSQLStatement.Text = "ERROR: " + ex.Message;
            //return;
        }

        // Set them now:
        RastxtExpOpts.CharactersPerInch = 20;
        RastxtExpOpts.LinesPerPage = 0; // this line causes the error

        // Save the udpated info
        if (RastxtExpOpts != null)
            rptClientDoc.set_SavedExportOptions(CrReportExportFormatEnum.crReportExportFormatText, RastxtExpOpts);

        CrystalDecisions.ReportAppServer.ReportDefModel.ExportOptions exportOpts1 = new CrystalDecisions.ReportAppServer.ReportDefModel.ExportOptions();
        exportOpts1.ExportFormatType = CrReportExportFormatEnum.crReportExportFormatText;
        exportOpts1.FormatOptions = RastxtExpOpts;

        // And Export
        rptClientDoc.PrintOutputController.ExportEx(exportOpts1).Save(outputFileName, true);
        MessageBox.Show("Export to Txt Completed", "", MessageBoxButtons.OK, MessageBoxIcon.Information);

    }
    catch (Exception ex)
    {
        btnSQLStatement.Text = "ERROR: " + ex.Message;
        return;
    }
}
