Ooops, I never noticed that, but bitmap is right, it's an html error, all you need to do is remove the colspan=4 from after the $avatarimage... so
Code:
<td bgcolor="#1C5780" align="center" valign="top" width="100">$avatarimage</td>
<td bgcolor="#13486D" colspan="4">
becomes..
Code:
<td bgcolor="#1C5780" align="center" valign="top" width="100">$avatarimage</td>
<td bgcolor="#13486D">
If you just remove that, nothing else will change but the line will appear properly.
I'll update the download
