在asp.net 3.5中实现Crystal报表时，加载报告失败

Im实现水晶报告，它是内置在visual studio 2008。当我创建我的水晶报告并检查其预览，它显示我的数据，但当我调用它在我的abc.aspx页面报告不加载和给出错误加载报告失败。
这是我的代码

Im implementing crystal report which is builtin in visual studio 2008. When i create my crystal report and check its preview it shows me the data but when i call it on my abc.aspx page report doesnt load and gives error 'Load report failed'. This is my Code

 <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" 
            AutoDataBind="true" ReportSourceID="CrystalReportSource1" />
        <br />
    <br />
    <br />
        <br />
        <CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
            <Report FileName="Reports/DailyPaymentStatus.rpt">
            </Report>
        </CR:CrystalReportSource>

可能会出错。此报告还接受4个参数，并且不在任何地方设置它们。还有一件事我想提一下，如果我做另一个简单的项目，并做同样的事情，它运行完美，并给我的输出。

what may be im doing wrong. This report also accept 4 parameters and im not setting them anywhere. Also one thing i want to mention if i make another simple project and do the same thing it runs perfectly and give me the output.
