Comment error on AnsPress

Hi,

When some adds a comment to a question or answer I get the following error:

Warning: Missing argument 2 for ap_comment(), called in /home/n4bb/public_html/wp-content/plugins/anspress/includes/anspress-form.php on line 594 and defined in /home/n4bb/public_html/wp-content/plugins/anspress/theme/default/functions.php on line 82

Warning: Missing argument 3 for ap_comment(), called in /home/n4bb/public_html/wp-content/plugins/anspress/includes/anspress-form.php on line 594 and defined in /home/n4bb/public_html/wp-content/plugins/anspress/theme/default/functions.php on line 82

The comments also show up really odd. You can see this at:

Can you please help me determine how to fix? Thanks!
