Every few months (more or less) a new version of Zen Cart is released, with new features and fixes for problems that have been found. Even if you don't need the new features, it is always good to upgrade so your cart will work its best and be secure.
If you don't have a custom template, your customizations will be erased when the new files are loaded. The custom template (override) system keeps your customized files in a safe place where they will automatically be used when they are needed.
The Classic template was intended only for people upgrading from old versions of ZC and is not really suitable for building a new store.
If you have already altered the Classic template files to your liking, the simplest fix would be to copy all /classic/ folders and the files in them and rename the copied folders to /your_template/, then follow the directions in the FAQ for editing template_info.php and activating your template.
The *best* fix would be to apply your styling to a copy of /template_default/ or the free future_zen template you can download (button at top of page).
In your code snippet
<div id="navColumnTwoWrapper" style="width: <?php echo BOX_WIDTH_RIGHT; ?>"><?php require(DIR_WS_MODULES . zen_get_module_directory('column_right.php')); ?></div></td>
<?php
you would probably insert your link code before the </div>
...lumn_right.php')); ?><your link code goes here></div>
Good luck!
