You do not add that code to any hook.

There is already a plugin on global start.

You need to edit the plugin so it looks like this (erase it all and paste this in)

function ieversion() 
{
  $match = preg_match('/MSIE ([0-9]\.[0-9])/',$_SERVER['HTTP_USER_AGENT'],$reg);
  if ($match == 0)
    return -1;
  else
    return floatval($reg[1]);
}

if (ieversion() < 9.0)
{
  $is_livetopic = true;
  $livetopichook = 'template_edits';
  include 'includes/livetopic_hooks.php';
}

Then change the line

if (ieversion() < 9.0)

to one of the conditions I posted above.

If that doesn't work then I'm sorry but this is a notoriously difficult mod to get working and why no one has produced a great working clone. A couple people have tried but they all seem to have their issues.
