@freewpress,
1. copy file loop-search-reply.php to your theme folder
2. Open it and find <?php bbp_reply_content(); ?> in line 57 or near it.
Change it with

<?php if ( !post_password_required(bbp_get_reply_topic_id()) ) {  bbp_reply_content();  }
else {
?>
<span class="your_message_class">Sorry, you can't read this reply.</span>
<?php } ?>

Anyway, I hope the plugin authors check this issue.
