Update issue

Anyone run into this Acrobat update issue??
 
I'm running Acrobat PRO 7.0.3 and when I "check for updates" I get a "no
updates available" message. I tried downloading the update manually,
only to see a "invalid application selected" when I point to the app. I
need to get this update out of the way before going onto 7.0.7, then
7.0.9.
 
Any idea what is going on?? I have another copy of Acrobat PRO on
another Mac running 7.0.9 with no problems. On this Mac, "check for
updates" works as it should.
