Logo Not Appearing in Internet Explorer

[SpongeFreak52]

I'm not really sure what happened, but I had updated to vB 3.7 Beta 5 today, and just a while ago when I first checked it with IE (because I normally test on FireFox), there was no logo!

Just in case it helps, I have vBAdvanced installed, with the portal set as index.php.

Here is my current header code:

<table border="0" align="center" cellpadding="0" cellspacing="0">
  <tr>
    <td><a href="index.php"<img src="http://game-spin.com/images/shutter/logo.png" width="550" border="0"></a></td>
  </tr>
</table>


<table width="90%" cellpadding="0" cellspacing="0" border="0" align="center" >
<tr>

<td width="100%" valign="top">

<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td width="66" height="38"><img src="images/shutter/shutter-left-up.gif" width="66" height="38"></td>
    <td height="38" background="images/shutter/shutter-middle-back.gif"><div align="right"><img src="images/shutter/shutter-middle-image.gif" width="13" height="38"></div></td>
    <td width="37" height="38"><img src="images/shutter/shutter-right-up.gif" width="37" height="38"></td>
  </tr>
  <tr>
    <td valign="top" background="images/shutter/shutter-left-back.gif"><img src="images/shutter/shutter-left-image.gif" width="66" height="135"></td>
    <td valign="top" bgcolor="#dee0e7">
<!-- content table -->

$_phpinclude_output

Thanks for the help, hopefully someone knows what the issue is...
