Membership Plugin and Some Big Challenges

Hi,

I downloaded the membership lite plugin for wordpress. I've been trying to configure it, and the farther I get into doing so the more issues I have. The main page of my site is currently "broken" and I can't figure it out. That's why I paid the $49 to hopefully get your help. Here's the link to the mainpage of my site:

as you can see, things are a little messed up, and it's displaying the Protected Content message in the middle of the page. When I log into the site, most of the problems go away. The odd thing is, I've made sure to allow the public to see all pages that would be accessed from the main site. I'm pretty sure.

Also, should I download the pro version of the plugin now that I've paid for it? And if so, can i maintain my settings?
