Admin/Polls Page Throws Error (MVC Version)

I am receiving the below error when trying to access admin/polls.  The error is thrown before the controller is even hit, not sure how to track down the problem.

I have not modified anything from the source code I downloaded from this site.  I have however, converted this project to a 2010 project, but left the framework targeted at 3.5.

The route is setup as:

                new { controller = "Poll", action = "ManagePolls", page = 1 }


The ManagePolls action in the PollController is:

[Authorize(Roles = "Editor")]
        public ActionResult ManagePolls([Default(1)]int page)
            TheBeerHouseDataContext dc = new TheBeerHouseDataContext();
            var viewData = dc.Polls.GetPolls(null, page);

            ViewData["PageTitle"] = "Manage Polls";
            return View(viewData);

Update:  I downloaded the project again and did not upgrade the project to 2010.  It works now.  Would still love to hear if anybody knows how to resolve this issue.  If not maybe I'll know how to resolve it by the time I get though the entire book.
