While we prepare a fix for the issue we have disabled the downloads of SP2. Unfortunately disabling the SP2 file had the side effect of removing the description page - so the URL in the blog post will go to a &#39;404 - page not found&#39; page for now. As soon as the fix is available the SP2 download will be made available again, and the download page will start working.</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3334017" width="1" height="1">
