Thanks for your advice. I definitely would rather not skip another cycle if at all possible. Do you feel that it would benefit me to send an update to Maryland? My adviser got in contact with the associate dean of admissions there and she responded to him with an email saying I can contact her with any questions, but I don't really know what to say to her at this point. I feel like the only appropriate response would be to provide her with an update, because my only questions at this point would be "why didn't you interview me" and "what can I do to convince you to interview me," and I'm not sure whether either of those are questions that she would be allowed to answer.
I wouldn't ask those questions of the dean.
I would provide a non-whiny, non-desperate update of significant accomplishments not previously reported. Gonnif has posted elsewhere about how too many updates sound whiny and desperate.
Take a matter of fact approach in your update and don't waste time by belaboring the obvious fact that you remain interested in the school.
