Crystal Reports Export Problems

Hello Experts,

I have problems exporting Crystal Report in my .NET Application, whenever I try to export it throws an javascript error on my report viewer. I have CR2008 Runtime installed on the machine and also I checked forums before posting here. All the files are located in this path:C:\inetpub\wwwroot\aspnet_client\system_web\2_0_50727\crystalreportviewers12.

The 'Object Expected' error occurred, I tried using Process Monitor tool to find what Javascript its running.It complains this:

PATH:
C:\inetpub\wwwroot\aspnet_client\system_web\2_0_50727\crystalreportviewers12\js\crviewer\
crv.js\web.config

RESULT:
PATH NOT FOUND

The JavaScript error fails here:

var __CRYSTALREPORTVIEWERONSUBMIT12=__doPostBack;__doPostBack=function(t,a)
{bobj.event.publish('saveViewState');__CRYSTALREPORTVIEWERONSUBMIT12(t,a);}function 
WebForm_OnSubmit() {
bobj.event.publish('saveViewState');
return true;

Actually, it was 2 JS errors, both point to this same location:

1. ';' Expected (After loading Report).

2. Object Expected(When tried clicking on Export).

Any guess, what I'm doing wrong???
