Custom Post types with Pay-Per-View

i have installed pay per view and configured it correctly, the plugin works on regular posts and pages, however i will be using it on my custom post types, and it will not work on these pages. i am using Advanced Custom Post Types plugin to make my post types. I tried to implement your “customization” edits to the theme files but it would not work and caused a fatal error. it seems to conflict with the pluggable.php included in wp-includes.

please help
