Patience. There are lots of students who receive multiple acceptances and, inevitably, they can only attend one med school, right?
By April, but definitely by May, some people will cancel their acceptance to AE and that frees up the ADCOM to take people off their wait list. From their perspective, they cannot offer more acceptances than current positions in their first-year class. Patience.
Things you can do:
1) Send transcript
2) Send letters of intent detailing your interest in the program
I liked their program so it's worth the wait.
Good luck!
