Hi Wayne,
You are using Joomla! 2.5, therefore Admin Tools is looking for an ID of 42 (that's the default SA ID in Joomla! 1.6 and later). Since this is not used, there is nothing for Admin Tools to change. I know, I know, you are using the default SA user of your migrated Joomla! 1.5 site. That's not a problem. Really. All you have to do is make sure that you rename the username (if it's still "admin") to something else.
