Board Closed / cant reopen (no longer admin)

[Steele Kizerian]

My wife and I had a board and apparently it was closed: https://trello.com/b/0oPHqBMC

We are the only ones on that board (that we are aware of) unless somebody got a hold of it. We want to re-open it but apparently we are no longer admins on the board. It is called LTD: Christ Light Book. We had so much content and data there for our book and its all gone. How do we go about re-opening it? Who does it say is the admin now? This is very important to us. Can we get access again and be made the admin?
