If u getting the message of Using Older Version on Server then u have to restart the server application.
because while u was starting the server it was showing the message of the update version on next run..
so after restarting the server application updates gets applied.
And if u getting the Message of Using Older Version on Client then U have to refresh the ERA explorer using refresh Button which was provided on the top right hand side. By this the explorer get the same Version as on server.
Always Remember Both Client n server Version should b same.
