Ok, so I did a little seaching on their mailing lists and found my answer,
For anyone who might have the same problem as me, all you need to do is
1. Copy the libpdf_php.dll from the bind/phpX folder (where X == your php version) to your extensions folder (this is specified in your php.ini file)
2. Edit your php.ini file: A. Comment out the
extension=pdf.dll line and add
extension=libpdf_php.dll
3. Save the php.ini file and restart apache (some computers may not require this while others may require a full system reboot)
And that is all. Thank you for all the help
