I presume my last post has not been approved yet, but as I do not want to forget posting this possible vital information, here goes...
I did a quick forum search below for DirectX SDK and found...

which had a link to this...
http://forum.thegamecreators.com/?m=forum_view&t=176637&b=22
which featured this download...
http://samoatesgames.com/downloads/TGC/DGDK_2010_(DX_June_2010)_02-11-2010.zip
it is a recompiled version of the 2010 June SDK for GDK... maybe this can be of some use to you?
I have also begun an archive process for every DirectX Redist / DirectX SDK I can find as it looks like MS have decided not to host them any longer... if you have any of the 2006 / 2007 SDKs please let me know.
EDIT
OH YAY I did not actually double post, and my post moderation has ended yay
