sorry, prematurely submitted that. Let’s try again.

I set up a field group using the code as a reference and inserted your code into the template without making any changes to it. The result of my test is here: http://www.ssird7.com.php53-14.dfw1-2.websitetestlink.com/2015/08/18/hello-world/ and it’s working for me.

Here is the exported field group I created:

<?php 

if(function_exists("register_field_group"))
{
  register_field_group(array (
    'id' => 'acf_test-group',
    'title' => 'test group',
    'fields' => array (
      array (
        'key' => 'field_56aaccc8f9a22',
        'label' => 'downloads',
        'name' => 'downloads',
        'type' => 'repeater',
        'sub_fields' => array (
          array (
            'key' => 'field_56aacd07f9a23',
            'label' => 'downloads_title',
            'name' => 'downloads_title',
            'type' => 'text',
            'column_width' => '',
            'default_value' => '',
            'placeholder' => '',
            'prepend' => '',
            'append' => '',
            'formatting' => 'html',
            'maxlength' => '',
          ),
          array (
            'key' => 'field_56aacd10f9a24',
            'label' => 'documents',
            'name' => 'documents',
            'type' => 'repeater',
            'column_width' => '',
            'sub_fields' => array (
              array (
                'key' => 'field_56aacd30f9a25',
                'label' => 'document_upload',
                'name' => 'document_upload',
                'type' => 'file',
                'column_width' => '',
                'save_format' => 'object',
                'library' => 'all',
              ),
              array (
                'key' => 'field_56aaceeb47f43',
                'label' => 'document_name',
                'name' => 'document_name',
                'type' => 'text',
                'column_width' => '',
                'default_value' => '',
                'placeholder' => '',
                'prepend' => '',
                'append' => '',
                'formatting' => 'html',
                'maxlength' => '',
              ),
            ),
            'row_min' => '',
            'row_limit' => '',
            'layout' => 'row',
            'button_label' => 'Add Row',
          ),
        ),
        'row_min' => '',
        'row_limit' => '',
        'layout' => 'row',
        'button_label' => 'Add Row',
      ),
    ),
    'location' => array (
      array (
        array (
          'param' => 'post_type',
          'operator' => '==',
          'value' => 'post',
          'order_no' => 0,
          'group_no' => 0,
        ),
      ),
    ),
    'options' => array (
      'position' => 'normal',
      'layout' => 'no_box',
      'hide_on_screen' => array (
      ),
    ),
    'menu_order' => 0,
  ));
}

and here is the code in the template, which is just a copy of yours

if( have_rows('downloads') ): ?>
  
  <div id="downloads">
    <?php
      // loop through rows (parent repeater)
      while( have_rows('downloads') ): the_row();
    ?>
    
    <div class="downloads-title">
      <h3><?php the_sub_field('downloads_title'); ?></h3>
      <i class="downloads-border"></i>
      
      <?php
        // check for rows (sub repeater)
        if( have_rows('documents') ):
      ?>
        
      <ul class="fa-ul">
        <?php
          // loop through rows (sub repeater)
          while( have_rows('documents') ): the_row();
        
          // display each item as a list - with a class of completed ( if completed )
          $file = get_sub_field('document_upload'); 
        ?>
        
        <li><i class="fa-li fa fa-download"></i><a href="<?php echo $file['url']; ?>"><?php the_sub_field('document_name'); ?></a></li>
        
        <?php endwhile; ?>
      </ul>
      
      <?php endif; //if( get_sub_field('documents') ): ?>
    </div>
    <?php endwhile; // while( have_rows('downloads') ): ?>
  </div>
<?php endif;
