You need to be careful about the order in which you declare your routes. Since there is no common element to a /{username} URL, you need to declare it as the last ‘catch-all’ route, after all of your specific routes.

RouteTable.Routes.MapRoute(null, "LogIn", new { controller = "Account", action = "LogIn" });
RouteTable.Routes.MapRoute(null, "LogOut", new { controller = "Account", action = "LogOut" });
// ... other routes go here ...

// Final catch-all route to map /{username} to the Account.Details action.
RouteTable.Routes.MapRoute(null, "{id}", new { controller = "Account", action = "Details" });

It’s also worth remembering that you need to extend your validation on usernames to prevent people from choosing names that conflict with the specific routes (e.g. LogIn).
