Exception when ReportDocument is Exported, Saved, or Printed

Question

This one might be a tough one to explain. I've got a program which fills in a pre-built Crystal Report (CR 2011) based on an Oracle Database. I've applied the logon information to all the tables in the report (and all the tables in the 5 sub reports) through MSDN tutorial based code. If I do not add any code to do anything with the report once it's refreshed (such as saving it, or sending it to a printer) it will run through my code without issue. However, if I add any code that makes the program useful, it breaks with the below Exception.

Here is my relevant code:

    try
    {
        for (Intcount = 1; Intcount < rName.Count(); Intcount++)
        {
            LogFile.LogMessage(path, sReportPath);
            LogFile.LogMessage(path, sReportPath + rName.ElementAt(Intcount));

            //This line is loading "C:\...\Policy Reinstatement.rpt" which is valid
            cr.Load(sReportPath + rName.ElementAt(Intcount));

            crConnectionInfo.ServerName = sDataSource;
            crConnectionInfo.DatabaseName = "";
            crConnectionInfo.UserID = sUserID;
            crConnectionInfo.Password = sPassword;

            cr.SetDatabaseLogon(crConnectionInfo.UserID, crConnectionInfo.Password,
                crConnectionInfo.ServerName, crConnectionInfo.DatabaseName);

            //Method for looping through each table in the report
            //and applying the Connection Info to each of them
            SetDBLogonForReport(crConnectionInfo, cr);
            //Method for looping through all SubReports,
            //then calling the SetDBLogonForReport method.
            SetDBLogonForSubReports(crConnectionInfo, cr);

            CrystalReportViewer rpt = new CrystalReportViewer();
            rpt.ReportSource = cr;
            try
            {
                rpt.Refresh();
            }
            catch (Exception ex)
            {
                //It does not throw on this exception
                LogFile.LogError(path, ex);
                throw;
            }
            cr.PrintToPrinter(1, false, 0, 1);
        }
     }
     catch (Exception ex)
     {
         //It throws on this exception
         LogFile.LogError(path, ex);
         throw;
     }

Here is the exception:

Thanks in advance for your help.
