PHPmailer help

[zfred09]

I posted this once in third-party scripts, but no one seems to look at those threads so I reposted here. Anyways when using phpmailer through a smtp I get this error message: [color=red]Mailer Error: Language string failed to load: recipients_failed[/color]
I have searched for at least a couple hours for the solution to this problem, have tried many different fixes and still no result.  How do I fix this problem?
[code]
                                ini_set("include_path", ".:/path/to/phpmailer/dir");
ini_set("include_path", ".:/path/to/smtp/dir");
ini_set("include_path", ".:/path/to/phpmailer.lang-en/dir");
                                $mail = new PHPMailer();

$mail->IsSMTP();                                      // set mailer to use SMTP
$mail->Host = "smtp.mydomain.com";  // specify main and backup server
$mail->SMTPAuth = true;    // turn on SMTP authentication
$mail->Username = "username";  // SMTP username
$mail->Password = "pass"; // SMTP password

$mail->From = "[email protected]";
$mail->AddAddress("[email protected]");

$mail->Subject = "Blah";
$mail->Body = " Email text"; [/code]
