See if the solution here helps you:

Also, not sure about this, but I haven't got time to look at it: rd.Load(Server.MapPath(@"~\Reports\Inventory\CrystalReportTest.rpt"));

Check the value returned by Server.MapPath and see if the report actually exists in that location and is visible when you click on the print or zoom button.

If you use a hardcoded path to a report in a test, does it work?
