trouble with running a captcha script

[ftbaker]

My website is being overrun with spam and I am trying to install a php captcha script. I have installed php 5 on my website askthephysicist.com which is hosted on a 1&1 Windows server, but I think the problem is that I do not know where to point my script to find the lib. I have very little fluency with any scripting languages. Anyhow, the beginning of the script reads:

<?php

require 'CaptchasDotNet.php';

// Required Parameters
// Replace the values you receive upon registration at http://captchas.net.
//
// client: 'demo'
//
// secret: 'secret'
//

and when I run it I get the message:


Fatal error: require(): Failed opening required 'CaptchasDotNet.php' (include_path='.:/usr/lib/php5.5') in /homepages/29/d191906528/htdocs/askthephysicist/query.php on line 4


The whole code may be found at http://captchas.net/sample/php/ if that is helpful, but the error occurs with the first statement require 'CaptchasDotNet.php';

php tries to open the file CaptchasDotNet.php but was not able to find it. Did you save the file in the same directory where this script is?
