Try uninstalling that Adobe update and see if it helps?

Edit
Also can you provide the link from where you downloaded the link?
There is no link... I updated CS3 from within the application itself. I opened Photoshop (or Illustrator...), go to Help menu and click on "Update". Adobe updater starts and checks for any updates. If there are, it will show a list of available updates from which I can choose to download and install. I select all of them every time.
