Now I've managed to find just 1 (free) extension that claims to do this, but when I have installed it, all works fine on the backend, but no reply is visible on the front end

The extension in question is: http://www.opencart.com/index.php?route ... 20directly
I'm sure to get it working with my site, it just requires a slight tweak to the code here and there inside the xml file, but unfortunately I'm no coder.
Here's a snippet of the error code in my vQmod manager:
=========================================================================================
MOD DETAILS:
modFile : /home2/**********/public_html/************.com/vqmod/xml/aboc_reply_to_review.xml
id : Reply to review
version : 1.0.0
vqmver : 2.4.1
author : ab-oc 09.2014
File Name : catalog/view/theme/*/template/product/review.tpl(0)
VQModObject::applyMod - SEARCH NOT FOUND (SKIPPED): <div class="review-list">
=========================================================================================
For anyone interested, my site is running OC 1.5.6.4 and the Journal 2 theme.
Now you may be wondering, why don't I just contact the developer of this extension and ask them for their advice, right? Well I have (or at least posted the problem on the extension page) but it seems like they don't support it any longer looking at the dates they last replied to some of the posts, and there's no direct contact information for him/her, hence this thread post.
So in a nutshell, is there any kind soul/coder out there who is willing to point me in the right direction on which bits of the code needs changing to get this extension working on my site. Or alternatively, I'm willing to pay someone if need be

Look forward to your replies...
Cheers,
Mark
