Classes "accidentally" dropped by Registrar

I am a student at Baruch and today I was told that the registrar dropped all my courses - something about my financial aid not showing yet (no warning sent or anything). Yesterday night I checked my schedule and everything was fine, and today all the classes were gone. I went to the office to see if they can fix it, and they said the classes are full now and there’s nothing they can do. I have to take an extra class which I don’t need this semester, along with multiple extra classes next semester, just so I can qualify for financial aid. I was all set to graduate this semester and had a job lined up. Is there anything I can do?
