multisite wp-signup.php is missing.

I am using MEmbership Pro and Pro sites, but I can't get anything more than a 404 and the url says this: http://petsliveon.com/protected-content__trashed/?redirect_to=http%3A%2F%2Fpetsliveon.com%2Fpro-site__trashed%2F%3Faction%3Dnew_blog

I've made sure you can register. I feel like I have some conflict but need both plugins.
I sure hope you can help me and that this is an easy fix!

I unprotected everything in Membership in an effort to make this work.
