Have you coded your own addins, or used VSIP? It sounds like a VS COM DLL may have been unregistered by mistake. That often happens when people develop addins and do a bunch of installs/uninstalls. If that's the case, it's an easy fix, but you have to find the right DLL and register it. VS uses COM DLLs to tell it how to handle different types of projects (VS wasn't written in a managed language, so it has all the COM issues we love to hate).

TheBeerHouse is supposed to work with the Web Express product. It's just one big project with no separate class libs. It uses the app_code folder to hold many of it's objects that would otherwise be in separate projects.
