DD4t 2011 site, doesn't hit page controller & keeps getting 404

Question

I have a DD4T 2011 site. I get a 404 for every URL & no requests are going to the page controller. Any ideas on what the issue could be? runAllManagedModulesForAllRequests="true" is in web.config. Could this be a license issue? I found the entry below in the log, so it looks like the license is ok. I don't see any errors in my log

2014-08-05 14:15:20,460 DEBUG LicenseReader - Found license entry for Tridion CD Broker, trying to validate this license key
2014-08-05 14:15:20,460 DEBUG LicenseReader - There was no licenseLock Location specified, using user.home var: C:\

2014-08-05 14:15:20,460 DEBUG LicenseReader - Found Key Tridion CD Broker, Value true

Update

These are my route entries. I commented out the site edit config for now. This looks like a straight MVC issue, not a DD4T one.

    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    /////Route for SDL Tridion UI 2011 (Aka !SiteEdit)
    //routes.MapRoute(
    //    "SiteEditBlankPage",
    //    "se_blank.html",
    //    new { controller = "Empty", action = "Index" });

    //Tridion page route
    routes.MapRoute(
       "TridionPage",
       "{*PageId}",
       new { controller = "Page", action = "Page" }, // Parameter defaults
       new { pageId = @"^(.*)?$" } // Parameter constraints
   );


    routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters
        new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
    );

Finally found the issue. I'd linked the project to MVC 4. The version of DD4T for tridion 2011 must use MVC 3. What threw me was that there was no specific error that I could find, I just got a "page not found" error.

Per Rob Stevenson-Leggett, make sure you are using DD4T 1.30 or later if you want to use MVC 4 or 5.
