Membership Plugin Broke My Site

Hello,

I downloaded and installed the Membership Plugin and immediately after installation there was a 500 Internal Server Error and I could not access the backend of my site. I had to delete all of the Membership plugin files via FTP in order to regain access to my site. I am using the latest version of WordPress and Genesis. Please let me know if your plugin is not compatible so that I can be refunded, otherwise please let me know why it is not working.

Thank you.
