Sharebar Creating errors

I have just installed Sharebar in my wordpress blog (3.5) & it’s creating bunch of error on all the posts.

This is the error I am getting

Warning: Missing argument 2 for wpdb::prepare(), called in /home/********/public_html/******.***/wp-content/plugins/sharebar/sharebar.php on line 112 and defined in /home/*********/public_html/************.***/wp-includes/wp-db.php on line 990

Can someone tell me what’s wrong? I mean have I not configured it properly or is there any problem with plugin?
