Recent Global Posts Widget - Need help

I installed the plugin, it's count posts in database, but...
1.I don't see admin panel for this plugin, so I can't configurate it.
2.Then I put function widget_recent_global_posts() on my home page home.php I get follow:
Warning: Missing argument 1 for widget_recent_global_posts(), called in /wp-content/themes/home/home.php on line 95 and defined in /wp-content/mu-plugins/widget-recent-global-posts.php on line 141

Warning: extract() [function.extract]: First argument should be an array in /wp-content/mu-plugins/widget-recent-global-posts.php on line 143
