VS 2012 with Crystal Reports 13 having report.load(strFileName) issue

        using (ReportDocument repDoc1 = new ReportDocument())

        {

            DateTime dteStart = DateTime.Now;

            dteDoneFlag = dteStart;

            repDoc1.Load(strFileName);

            DateTime dteEnd = DateTime.Now;

          storeDelay(fcnDelayed(  dteStart,dteEnd));

     ...

     }

public static string fcnDelayed( DateTime dteStart, DateTime dteEnd)
        {
            TimeSpan strDiff = (dteEnd - dteStart);
            string strMinutes = strDiff.Minutes.ToString();
            string strSeconds = strDiff.Seconds.ToString();
            string strMilSeconds = strDiff.Milliseconds.ToString();
            return strMinutes + "Min" + strSeconds + "Sec" + strMilSeconds + "MS since: " + dteStart;
        }

I tried every solution I could find, to include subreport, printer, and running a throw away report, but no consistant solution was found.  Threading one report first seems to help the latter most of the time but still undependable. 

Your help will be greatly appreciated.
