I suspect that this is related to your other problem (namely that .aspx pages are not mapped to the ASP.NET ISAPI Extension .dll). So it's being served as a plain HTML page with no server-side processing, including no server-side processing of #include directives. In any case, for items like navigation, I think you're better off using a user control rather than an include.
