Membership plugin - My menus disappear when I'm not logged in.

I've just installed Membership and I'm testing my level filters prior to setting up subscriptions and have two basic levels "free users" and "premium" I put all of the categories that I want to be accessible to everyone who visits the site in the Positive section, nothing in the negative section and set the Strangers level to "free users". However, if I'm not logged in the menu disappears. So visitors are locked out.
Also the shortcodes don't work, the shortcode just appears as text in the Page.
I saw a post where this was addressed menu issue but unfortunately Barry, logged into the site and fixed the guy's problem so I don't know what the solution was.
