Membership Roles Bulk Assigned and Now Admin has No Access to Admin Features

Hi, I used the bulk assign option to give all 377 users of my site access to our "Members Only" section. I included myself in this process, adding the subscription "Members" to each user. Immediately after doing this I lost access to all dashboard features except for "Profile" and "Membership." I no longer have access to users, plugins, template features, etc. How do I fix this? I cannot enable support to WPMU Dev because the support plugin is gone too. Thanks.

Solutions tried:

1 - Added this line to the wp-config.php file:
define( 'MEMBERSHIP_MASTER_ADMIN', 'admin');

2 - That enabled me to see the menu items that were missing, but the backend WP functions are still missing. Where do I look in the database and what do I edit? I need to remove the access level and subscription and change it to "SuperUser". In the user section the admin is set to 1 under user_status and all others are set to 0.
