Hi, after correctly created config.php in theme root directory, you should see just default wordpress icons in visual editor (and icons of some plugins in case you are using some which add icon there). Disabled are just our icons, so you have to insert shortcodes from our preview site, or you can find shortcodes here http://www.ait-themes.com/doc/shortcodes/ (there are all our shortcodes, also from other themes, so you cant use each shortcode listed in mentioned documentation page) you can find there examples of Menu shortcodes etc...
If you have still problem with implementing config.php file, feel free to contact me with your ftp and admin credentials and I'll do it for you. Thanks, Ivan.
