0	Good Afternoon Abhi_patil Have you got a machine key specified in your web.config? It might be corrupted or missing some data. The machine key has to be a specific length and if it is missing characters then it will fail. Try to remove the machine key section from the web.config and see if this stops the error. Then you at least know if this is the cause.
