MSDN library for Visual Studio 2008 SP1 is already available for download, if you haven't downloaded it yet, go and download it. The original 90-day MSDN version of vstm2008 is not complete. There is no post SP1, this should be enough. I have installed it successfully, there are many more SP1 things, but I haven't had time to see the others.
