Your probably better off making your own contact form if your not familiar with a lot of editing for php. There are a lot of simple forms that you can create quickly.
<?php
// Subject and e-mail variables
$emailSubject = 'Whatever Subject you want';
$webMaster = 'Your E-mail';
// Variables that you want included in e-mail
$emailField = $_POST['email'];
$body = <<<EOD
<br><hr><br>
Email: $emailField
$headers = "From: $emailField \r\n";
$headers .= "Content=type: text/html\r\n";
if (!(mail($webMaster, $emailSubject, $body, $headers)))
{
echo "Mail error...Please try again later!";
die();
}
// results rendered as html
$theResults = <<<EOD
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Confirmation</title>
</head>
// Confirmation Page
<body>
<p align="center">Thank you!
</p>
<p align="center">We have received your application, you will be contacted within a few days.</p>
<p align="center"> </p>
<p align="center"><a href="forum.php">Forums</a></p>
</body>
</html>
EOD;
echo "$theResults";
?>
Not the best, but it should get you on the right track.
