No, at the moment that is going to stay my rating, mainly due to the fact that I spent a day and a half fighting with the plugin, and the project I am working on have a very strict deadline.
If you guys write up documentation on how to do custom loops for developers I will increase my rating.
You actually do, I just had to go looking through your plugins folder for the file where you guys create the custom post type. For anyone in the future this is my arguments to loop through the All-in-one Event Calendar Post by Categories:
$eventArgs = array(
'post_type' => AI1EC_POST_TYPE,
'events_categories' => 'featured_event'
);
If anyone wants to know field to target, I recommend looking through the custom post type php file in the Plugins Folder.
