Lost super admin rights

Boy did I mess up. I accidentally lost admin right using easyblog. I did not think easy blog used joomla ACL and I like a big dummy changed my super admin rights to author in easy blog for the ABYA author. Now I can't login to joomla backend. I looked in the database using phpmyadmin and could not find prefix_users. I don't have enough SQL experience to fix this problem. I feel that there should have been a warning from easyblog stating are you sure you want to change admin rights or something. Can you please help!!!
