No, you don't want to remove it.
Currently, you have it inside a table:
HTML Code:
<script type="text/javascript">
<!--
// Main vBulletin Javascript Initialization
vBulletin_init();
//-->
</script>
</td>
</tr>
</table>
</td>
</tr>
</table>
Take it outside the table:
HTML Code:
</td>
</tr>
</table>
</td>
</tr>
</table>
<script type="text/javascript">
<!--
// Main vBulletin Javascript Initialization
vBulletin_init();
//-->
</script>
