CentraSite Errors

Just installed centrasite community edition to try and if you try and add an association you get a 404 error “The requested resource (/PluggableUI/servlet/AddKeywordAssociation.html) is not available.” And the advanced tab gives the 404 error “The requested resource (/PluggableUI/servlet/AddAdvancedAssociation.html) is not available.”

Is there a way to fix this?
