Arcade

[ringnews24]

Ive installed the arcade, and the options appear on the right hand side of the admin CP.

The install guide says

In this navbar-Template search for:

<li><a href="calendar.php{vb:raw session.sessionurl_q}">{vb:rawphrase calendar}</a></li>

below add

<li><a href="arcade.php{vb:raw session.sessionurl_q}">Arcade</a></li>

-------------------------------------------------------------------------------------------------------------------

<li><a href="calendar.php{vb:raw session.sessionurl_q}">{vb:rawphrase calendar}</a></li>

That line doesnt not appear in my navbar, what do i do next?
