crystal reports shows only hexa decimal code

Question

Im working on Visual Studio 2008 to develop a web application in asp.net.

if I add a crystal report file (.rpt) in my project, I see only hexadecimal code.

I obviously miss something, previously it worked in my system..recently i formatted my system, and installed vs2008, then the problem arises...im in need..

Please help me to find the solution.. thanks in advance
