Bulk Order Dual Pricing ERROR HELP

Hey. I've been customizing my first zen cart install for my boss. I put on a bulk order module which is available from the download section

http://www.zen-cart.com/index.php?main_page=product_contrib_info&cPath=40_41&products_id=166

All was going well with the installation but when you try to view a product an error occurs. I need your help please. I think i just need one file. The package did not come with the file though!

here is the error.

Warning: main(includes/modules/pages/product_info/main_template_vars_images.php): failed to open stream: No such file or directory in /home/taprum/public_html/shop/includes/templates/classic/templates/tpl_product_info_display.php on line 103

you can view the site at http://taprumlive.com/shop

Please help. My boss walked out of the office.

I think I am just sol. Zen reinstall here we come.

It's calling for an obsolete file:
includes/modules/pages/product_info/main_template_vars_images.php

That file was removed and relocated as a module in v1.3. Thus, it would appear that one or more of your customizations re-introduced a request for that file because it was based on an older version.
