I've added a new menu item in the CP Admin menu (in cp2_lib around line 1200), but when I click on the option, I get the following error message:
<pre> The page and/or tab you requested is unavailable. The required code could not be properly loaded. Please ensure
that all scripts, libraries, and templates have been properly uploaded.
</pre>

I called the new page 'test' and uploaded cp2_test.pl (a copy of cp2_paths.pl) to my Templates directory. What other changes should I perform in order to display a page?
