Installation Membership error

I am having trouble with installing Membership, i've tried installing via WMPU Dashboard and also through FTP. But as soon as I activate the plugin the backend goes 'out', white screen with this error;

http://gepiept.nl/wp-admin/plugins.php?activate=true&plugin_status=all&paged=1&s=

Then I've got to delete the entire membership folder to be able to acces the backpanel again. Any help is welcome :slight_smile:
