Call to undefined method Config::getConfig() - php

Question

I'm testing the Flexpaper plugin on Windows XP running with XAMP, the issue is that it doesn't shows the pdf's, checking the php error log it says:
PHP Fatal error: Call to undefined method Config::getConfig() in
C:\xampp\htdocs\PDFViewer\php\services\view.php on line 24
The folder structure is: (omitting irrelevant files)
htdocs/
|->PDFViewer/
|->php/
|->admin_files/
|->config/
|->config.ini.win.php
|->lib/
|->common.php
|->pdf2json_php5.php
|->pdf2swf_php5.php
|->config.php
|->services/
|->view.php
Snippet of code of view.php
require_once("../lib/common.php");
require_once("../lib/pdf2swf_php5.php");
require_once("../lib/swfrender_php5.php");
require_once("../lib/pdf2json_php5.php");

And before you ask, yes, config.php do have the getConfig method
Edit: Added the config.php
<?php date_default_timezone_set('America/New_York'); ?>
<?php
class Config{

Answer 1

Modify the code snippet of view.php into:
$ds = DIRECTORY_SEPARATOR;
require_once("..{$ds}lib{$ds}common.php");
require_once("..{$ds}lib{$ds}pdf2swf_php5.php");
require_once("..{$ds}lib{$ds}swfrender_php5.php");
require_once("..{$ds}lib{$ds}pdf2json_php5.php");

Answer 2

Looks like I've made it work after adding C:/xampp/htdocs to the include_path variable in php.ini, and then just modified the require_once functions.
require_once section in View.php looks like:
require_once("PDFViewer/php/lib/common.php");
require_once("PDFViewer/php/lib/pdf2swf_php5.php");
require_once("PDFViewer/php/lib/swfrender_php5.php");
require_once("PDFViewer/php/lib/pdf2json_php5.php");
And the same for pdf2swf_php5.php, swfrender_php5.php and pdf2json_php5.php.
