SSO Console start service error

Nov 5, 2010 at 10:28 AM

Hi, I have successfully installed the server and deployed the webpart. However, when i add the webpart into the page, i can only see the title and no others. I check the SSO console and found there is an error as bellow. I tried to change the tcp port but got same error. Could anyone help?
