Powergallery v2 doesn't work on my client site - HELP

The PHP code I am to embed from Powergallery v2 is the following:

<?php
$pg_id = '3';
$pg_theme = 'PFR Theme';
include('/homepages/43/d333120063/htdocs/powergallery/galleries/flow/index.php');
?>

This works fine on my test site gallery.php

However, when I upload it to my client's hosting space (which is Linux and
supports php), it doesn't work and I get the following error:

Warning:
include(/homepages/43/d333120063/htdocs/powergallery/galleries/flow/index.php)
[function.include]: failed to open stream: No such file or directory in
/homepages/45/d400656386/htdocs/gallery.php on line 59

Warning: include() [function.include]: Failed opening
'/homepages/43/d333120063/htdocs/powergallery/galleries/flow/index.php' for
inclusion (include_path='.:/usr/lib/php5') in
/homepages/45/d400656386/htdocs/gallery.php on line 59


So, something is telling me that I'm missing something in the string of
code. I've tried changing it from 43 to 45, removing information, adding
php5, etc. and nothing appears to be working.

The actual site that I'm getting this error message is on
www.pfrclutchparts.com. Go to Gallery.

I have also changed the permissions on the PG_CachedResize_Image.php file as well as the admin-gallery/common/properties.php file and it still doesn't work.

I also deleted the test site thinking that the same gallery wouldn't work on two different sites, but that still didn't make a difference.

I changed the client site to use the external link so a web visitor can see the images, and there are no issues with this.

My other question is with regard to using this software on various domains. Do I have the ability to do so? I certainly hope so, as when I purchased this software, it didn't mention the limit on the number of domains I was allowed to use it on.

Please advise -
