Yep, I has similar problems after upgrading my Acrobat reader. I uninstalled and reinstalled the old Acrobat and it worked fine. Maybe download the latest CR service pack? On another note, it might not even be the new installation as much as maybe having old Acrobat files still left on your computer that didn't get uninstalled. Thus, there might be some DLL confusion. But anyway, you can play around with it and let us know if you came up with something else that works. But for me the problems went away after going back to the older version.
