Can't display categories since upgrading (1 post)

    I was using the following code in WP 2.0.7. I've upgraded to 2.7 and the code doesn't work any more, as I no longer get any categories diplayed. There aren't any errors I can see. Here's my blog: http://www.cygen.com/blog/. You can see Categories on the right side under Pages. All of the main categories appeared there. Clicking a main category allowed sub categories to appear under it. Any suggestions on what could have broken?

    <!-- start expand categories -->
    <li>
    <h2>Categories</h2>
    <ul>
    <?php
    $categories = $wpdb->get_results("SELECT * FROM $wpdb->categories WHERE category_count > 0 ORDER BY cat_name DESC"); // query database for categories with at least one post;
    
    $a = 1;
    
    foreach($categories as $category) : // start loop to display category list
    ?>
    <li>
    <a href="<?php echo get_category_link($category->cat_ID); ?>">
    
    <?php if (!is_category() || is_page() || $category->cat_ID === $cat){
    echo $category->cat_name;}
    else { echo"<font color=939392>" ;
    ?>
    
    <?php echo $category->cat_name; ?>
    </font>
    <?php } ?>
    
    </a>
    
    (<?php
     echo $category->category_count;
    ?>)
    
    <?php  /*echo is_category(); ?> <?php echo $category->cat_ID; ?> <?php echo $cat; */ ?>
    
    <?php
            if( is_category() && ($category->cat_ID === $cat) ) : // current category query is same as category presently in the loop
    ?>
            <ul>
    <?php
    
    $a = 1;
    $catq = new WP_Query("cat=$cat&showposts=-1"); // query posts from current category
    while($catq->have_posts()) : $catq->the_post(); // start posts in category loop
    ?>
    
    <li>- <a href="<?php the_permalink(); ?>">
    
      <?php
      if (($a % 2) == 1)
      { echo "<font color=3366ff>" ;}
      if (($a % 2) == 0)
      { echo "<font color=ff0000>" ;}
      $a = $a + 1;
      ?>
    
    <?php the_title(); ?></a> </li>
    <?php
                    endwhile; // end posts in category loop
    ?>
            </ul>
    <?php endif; // end current category query test ?></li>
    <?php endforeach; // end loop to display category list ?> 
    
    </ul>
    <!-- stop expand categories -->
