first and foremost:
I'm using Joomla! 1.0.12 and installing CB 1.0.2

I'm following all the instructions correctly, and I get to this stage:

8) Add a new user menu item for the comprofiler component
(this will be the users profile page).
For this, go to menu -> user menu, click New, select component,
then Community Builder (com_comprofiler), give a name and save.

but, when I select component, the option to select Community Builder won't show up

what should I do?
