Strange that your google search didn't direct you to this entry on the same wiki page that you reference above
When I logged in, I got this message - 1146 Table 'MY_DB.admin_menu_headers' doesn't exist - and no headers, so I couldn't go to Tools

This indicates that the tables used by Admin Profiles don't exist in your database. Most likely you have not run (successfully) the Admin Profiles installtion[sic] SQL.
Although that's not widely helpful, this is because the wiki can't know how you attempted to install the SQL patch. If you could provide some more details, maybe we ca work out why it didn't work for you.
