The report can not be loaded for SAP Crystal Server 2013 Evaluation

All , I was following the guide from  http://global12.sap.com/campaign/ne/free_trial/crystal_reports_server_2013/wty_int_crystal_reports_server_2013.epx?Level=1&FormResultID=60f087d7-4ab0-4efd-a30f-05933dac83ac&ContinueURL=%2fcampaign%2fne%2ffree_trial%2fcrystal_reports_server_2013%2findex.ep and try to integrate the SAP Crystal Reports for Enterprise and SAP Crystal Server 2013 SP1 Client Tools to work together. all of them are installed without problem. But every reports I build from Sap Crystal Reports for Enterprise can not be loaded in my test vs2010 project .

So I wondered if these two can work together well. because my test code is very simple. But unfortunatedly it failed. I have been working on it for couple of days. But does't get it work.  the code and exception shows below .Please review it .

protected void Page_Load(object sender, EventArgs e)
    {
        ReportDocument rpt = new ReportDocument();
        rpt.Load(Server.MapPath("~/test123.rpt")); // This line failed.
        System.Console.Write("ok!!!");

    }

the exception says :

Load report failed.

Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack.
