Custompress Cheatin' Uh message

I've just set up a custom post type and created a few taxonomies. When I attempt to click on the taxonomy names on the admin left sidebar (under my custom post type) I am greeted with the "Cheatin' Uh?" message. I haven't had this issue anywhere else.

Here's the url where I receive the message:
/wp-admin/edit-tags.php?taxonomy=artist&post_type=review

Is there something I can do to give myself permission to veiw/edit these pages?
I am enjoying the plugin so far and thank you for your help!
