Crystal report viewer operation timed out..

Hi

I am facing a time out problem while showing Crystal report in Crystal Report Viewer in .Net windows form. I have published crystal report document as web service and deployed it on webserver. in Crystal report viewer's report source i m passing asmx file's webpath. Every thing works fine but in some reports which takes time in querying data, viewer only waits for 90 second and after that it gives "Operation timed out." I have end found out its solution at Crystal report's website but i m not able to implement it properly. Viewer picks up timeout default value which is 90 seconds from EnterpriseReportService.asmx which is in .Net\Crystal Report\Viewers folder. Its already commented and it needs to uncomment and then set our own time out value in milliseconds. I have tried implementing it but its not working. you can see this problem at crystal report website at

Please let me know if any one has worked out this issue. Its a simple case of timeout but I am not able to implement at right place.

regards
Chander
