janeshh:

Public url is not available for this project.Can u suggest some other solution??..

i am dying to find the solution. what could be the problem?

i have created a new project and used the same dll and client files and its working perfectly fine.

But for my work project its not. Is it because my work project had version 5.3 before?. 

In that case also i have removed all the dlls and lic file of 5.3 from my bin folder.

Please help me.
