ibProArcade HELP?

i get to this instruction here:
click SAVE and edit the Template navbar (below "Navigation/Breadcrumb Templates")

it tells me to search for this line:
<li><a href="calendar.php{vb:raw session.sessionurl_q}">{vb:rawphrase calendar}</a></li>
and replace with this line:
<li><a href="arcade.php{vb:raw session.sessionurl_q}">Arcade</a></li>


the line doesnt exist for me, im running 4.2.2.

i see all the menus in admincp but nothing is on forums. www.bootyliciousgaming.net
