telligent version 8.5 , error This site has exceeded the licensed number of servers

In telligent version 8.5 , I am getting following error on my dev server.

This site has exceeded the licensed number of servers. You can access the site by opening it up directly on the server that is running the site. You can also manage your license by click here.

I have reduced the number of rows in  cs_Licenses_Servers but error is still there. Please suggest how to get rid form this error.

Thanks,
