Adobe Reader XI hangs on "receiving data" after submitting to php

Question

I am submitting PDF fillable form to php, then pdf is save & email to destination. It works, I receive the pdf filled file via email; However, in Safari works perfect redirects, etc. When using FireFox, Chrome, then Adobe Reader opens.
Then when submitting from Adobe Reader, it works fine, I receive the email with attachment.
The problem is that Adobe Reader hangs "receiving data" for a long time, then I get this message "An error occurred during the submit process. The network service you are trying to reach could not process the request."
I do get the file via email and it is fine. What is Adobe Reader waiting for?.
Thanks in advance

I do not think it is returning anything, here is the php code ...
<?php
$fileatt = date("d-m-Y-His") . ".pdf";  // Creates unique PDF name from the date
copy('php://input',"pdfs/".$fileatt); // Copies the pdf form data to a folder named pdfs
$fileatt = "pdfs/".$fileatt; // Path to the file gives the pdfs folder plus the unique file name we just assigned
$fileatt_type = "application/pdf"; // File Type
$fileatt_name = "Application Form_".$fileatt.".pdf"; // Filename that will be used for the file as the attachment when it is sent
$email_from = "mywebsite"; // Who the email is from
$email_subject = "Completed online Applications"; // The Subject of the email
$email_message = "Please find a recent online application attached.
$email_message .= "Any problems please email me...
"; // Message that the email has in it
$email_to = "[email protected]"; // Who the email is to
$headers = "From: ".$email_from;
//no need to change anything else under this point
$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($file);
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_message .= "\n\n";
$data = chunk_split(base64_encode($data));
$email_message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";
$ok = @mail($email_to, $email_subject, $email_message, $headers);
if($ok) {
unlink($fileatt); //NOW WE DELETE THE FILE FROM THE FOLDER pdfs
header("Location: return.pdf"); //where do we go once the form has been submitted.
} else {
die("Sorry but the email could not be sent. Please go back and try again!");
?>
