TeamSite 6.1 Service Pack 1 error

System

Just installed TeamSite 6.1 SP1 on Windows 2003. When I logged in CCPRO, I got error message:

No UI configuration found matching item ID iw.ccpro.workflow of type com.interwoven.ui.base.ui.config.Heading

The "Content" and "Workflow" tabs disappeared from the top part of the page.

Anyone had similar problem?!
