Crystal Reports: Fix for "Load report failed" error.

• Ensure the Report file name is correct (may be Typo or something. Example: Repotr1.rpt instead of Report1.rpt)
• Ensure the Report path is correct (Example: "Reports/Report1.rpt" instead of "~/Reports/Report1.rpt")
• Actually some of us forget to copy the report files to the publish folder (IIS virtual directory) so copy it.

protected void Page_Unload(object sender, EventArgs e)
{
  if(RptDoc != null)
  {
    RptDoc.Close();
    RptDoc.Dispose();
  }
}
