Unable to refresh jar .Using wrong port!!

I am getting a weird problem. I just finished with all installation and ran the configurator for workflow server. It finished properly. When I start the client, I get an error saying : Unable to refresh .jar from server.You may be using wrong port
If I say ok, I get the Authentication window, which authenticates properly and gives me the workflow tool. From here I am able to access Users, Monitor, Inbox, Administrator but not Designer and generator.

Any idea whats happening here… I have never heard of this… please help… its urgent!!
