Tricky to guess without seeing any code.
Here's some example code which fills and shows a report.
protected void Page_Load(object sender, EventArgs e)
ReportDocument rd;
DataTable dt = (DataTable)Session["xxxxx"];
// Tricky bit here is to make the name of the datatable match what the report expects
dt.TableName = "DataTable1";
rd = new ReportDocument();
rd.Load(Server.MapPath("Reports\\xxxxReport.rpt"));
rd.SetDataSource(dt);
rd.Refresh();
CrystalReportViewer1.ReportSource = rd;
CrystalReportViewer1.RefreshReport();
CrystalReportViewer1.DisplayGroupTree = false;
