I am having the same problem.
WP v3.6
Contact Form 7 v3.5.2
Contact Form DB v2.6.3
Download Monitor v3.3.6
Email Before Download v3.2.6
<?php wp_footer(); ?> in in footer.php
But I am getting the #wpcf7-f1819-p506-o1 at the end of the url address following submission which the forums suggest means ajax is not working?

I am also interested in this answer. I selected the cat id in the show posts when but it still archives all blog posts instead of just a single category.
