"using DevCow.Web.UI ;" -- error

Sep 10, 2011 at 4:25 AM

I receive the following errors in PageManagement.aspx.cs, role_manage_aspx.cs, role_view.asps.cs and ThemeManagement.aspx.cs when building the Extended Club Site Starter Kit site. 

The type or namespace name "DevCow" could not be found (are you missing a using directive or a using directive or an assemply reference?)

Please help.
