[Plugin: Advanced Export for WP & WPMU] Doesn’t work on WordPress 2.6.x

Plugin is activated but when you go to Manage > Advanced Export then you get

Fatal error: Call to undefined function screen_icon() in /var/www/domain.org/wp-content/plugins/advanced-export-for-wp-wpmu/ra-export.php on line 257

Is there any way around this?
