tried CS1.0 from codeplex on my CS 2008sp1, not working

it says it's for Community Server 2007!

I tried it on CS 2008 sp1, at first, it works.

I login with LiveId and Create a User, and login my CS.

but when I Logout and login again, error occured.

[NullReferenceException:
   CSLive.LoginLink.OnLoad(EventArgs e) +780
   System.Web.UI.Control.LoadRecursive() +47
   System.Web.UI.Control.LoadRecursive() +131
   System.Web.UI.Control.LoadRecursive() +131
   System.Web.UI.Control.LoadRecursive() +131

   System.Web.UI.Control.LoadRecursive() +131
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1061

so I should expect CSLive 2.0, sure?

Looks like a cookie issue
