I got my MPPA response first (earlier in March) and both my offers were in the first round. I spoke to the person handling admissions and they said that they have $0 budgeted towards entrance scholarships towards international students, so they couldn't do anything about it...
As for your application, I would probably call and email their office about it. I think the only reason why they got to my application was because I was being so persistent about trying to call them.
