CS6 Design Standard - Have License Key, Can't Find the Download

Hi there,

  I have my licensing key for CS6 Design Standard, but cannot find the software on the Adobe Download Assistant.  The closest thing I can find is 'Master Collection' (which I mistakenly downloaded, only to find my 'DS' key of course doesn't work for 'MC' ).  Where can I find the software for CS6 DS?

Thank you,
