You really should sort out your problems with the file download because it certainly ok. Anyway, just to help out here is the rest of it. Apologies for unnecessariy text hogging Admins .

2. Create a new template, with the name "showthread_replybox":
// ##################################################
<script language="javascript">
<!--
var postmaxchars = $postmaxchars;
function validate(theform) {
	if (theform.message.value=="") {
		alert("Please complete the message field.");
		return false; }
	if (postmaxchars != 0) {
		if (theform.message.value.length > $postmaxchars) {
			alert("Your message is too long.\n\nReduce your message to $postmaxchars characters.\nIt is currently "+theform.message.value.length+" characters long.");
			return false; }
		else { return true; }
	} else { return true; }
}
function checklength(theform) {
	if (postmaxchars != 0) { message = "\nThe maximum permitted length is $postmaxchars characters."; }
	else { message = ""; }
	alert("Your message is "+theform.message.value.length+" characters long."+message);
}
//-->
</script>

<form enctype="multipart/form-data" action="newreply.php" name="vbform" method="post" onSubmit="return validate(this)">
<input type="hidden" name="s" value="$session[sessionhash]">
<input type="hidden" name="action" value="postreply">
<input type="hidden" name="threadid" value="$threadid">
<input type="hidden" name="title" value="">
<input type="hidden" name="iconid" value="0">
<input type="hidden" name="parseurl" value="yes">
<input type="hidden" name="email" value="">
<input type="hidden" name="disablesmilies" value="">
<input type="hidden" name="closethread" value="">
<input type="hidden" name="hiddenreply" value="">
<input type="hidden" name="signature" value="yes">
<input type="hidden" name="rating" value="0">

<table cellpadding="{tableouterborderwidth}" cellspacing="0" border="0" bgcolor="{tablebordercolor}" {tableouterextra} width="{contenttablewidth}" align="center"><tr><td>
<table cellpadding="4" cellspacing="{tableinnerborderwidth}" border="0" {tableinnerextra} width="100%">
<tr>
	<td bgcolor="{tableheadbgcolor}" colspan="2"><normalfont color="{tableheadtextcolor}" class="thtcolor"><b>Post Reply</b></normalfont></td>
</tr>
<tr>
	<td bgcolor="{secondaltcolor}" valign="top" nowrap><normalfont><b>Your Reply:</b></normalfont></td>
	<td bgcolor="{secondaltcolor}">
		<table cellpadding="0" cellspacing="0" border="0">
		<tr valign="top">
			<td><textarea name="message" rows="7" cols="$textareacols" wrap="virtual" tabindex="1"></textarea><br>
			<smallfont><a href="javascript:checklength(document.vbform);">[check message length]</a></smallfont></td>
		</tr>
		</table>
	</td>
</tr>
</table>
</td></tr></table>

<br>

<table cellpadding="2" cellspacing="0" border="0" width="{contenttablewidth}" {tableinvisibleextra} align="center">
<tr>
	<td align="center"><normalfont>
	<input type="submit" class="bginput" name="submit" value="Submit Reply" accesskey="s" tabindex="2">
	<input type="reset" class="bginput" name="reset" value="Reset Form" accesskey="r" tabindex="3">
	</normalfont></td>
</tr>
</table>

</form>
// ##################################################

3. In the "showthread" template add $replybox right after the following:
// ##################################################
<!-- first unread and next/prev -->
<table cellpadding="2" cellspacing="0" border="0" width="95%"  align="center">
<tr>
	<td><smallfont>$pagenav&nbsp;</smallfont></td>
	<td align="right"><smallfont>
	<img src="https://vborg.vbsupport.ru/images/prev.gif" alt="" border="0">
	<a href="showthread.php?s=$session[sessionhash]&threadid=$threadid&goto=nextoldest">Last Thread</a>
	&nbsp;
	<a href="showthread.php?s=$session[sessionhash]&threadid=$threadid&goto=nextnewest">Next Thread</a>
	<img src="https://vborg.vbsupport.ru/images/next.gif" alt="" border="0">
	</smallfont></td>
</tr>
</table>
<!-- first unread and next/prev -->
// ##################################################

You're all done, now upload showthread.php back to your server and enjoy this hack. :-)
