"Download decoding failed" message - help!

Question

I've been trying to download a 40 MB file and once I've downloaded around 23MB of it, the download stops dead and I get a "Download decoding failed" message in my downloads window. The file works for other people so it must be a problem at my end. I've tried using Firefox as well, same problem. Does anyone have any idea how I can fix this?
Thanks!

I ran my contact.js through JSHint and fixed the errors that it came up with -- I also changed the action back to "". And .... it still hates me!  Here's my contact.js code, if interested!
    $(document).ready(function(){
      $("#send").click(function(){
        var name   = $("#name").val();
        var email  = $("#email").val();
        var message  = $("#message").val();
        var error = false;
         if(email.length === 0 || email.indexOf("@") == "-1" || email.indexOf(".") == "-1"){
           $("#error_email").fadeIn(500);
         }else{
           $("#error_email").fadeOut(500);
         if(message.length === 0){
            $("#error_message").fadeIn(500);
         }else{
            $("#error_message").fadeOut(500);
         if(error === false){
           $("#send").attr({"disabled" : "true", "value" : "Loading..." });
           $.ajax({
             type: "POST",
             url : "send.php",   
             data: "name=" + name + "&email=" + email + "&subject=" + "You Got Email" + "&message=" + message,
             success: function(data){   
              if(data == 'success'){
                $("#btnsubmit").remove();
                $("#mail_success").fadeIn(500);
              }else{
                $("#mail_failed").html(data).fadeIn(500);
                $("#send").removeAttr("disabled").attr("value", "send");
        }return false;
