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

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.
