Granting Access to Custom Post Types

I have created a custom post type using the standard WordPress codex. I’ve then created a new Membership Access Level and set two positive rules allowing this user to see the primary navigation item and one sub-navigation item. I’ve granted a new user the correct membership access level, but the custom post type menus are not showing.

I’ve read through the Membership 3.0 Documentation Page 40 Of 67, which addresses Access Levels but I do not understand how to get this working.

If you could spare some time to help me with this, that would be awesome.

Thank you as always, Troy.
