OUI in MA, 2nd time surrendered by probation officer, what is going to happen?

I got myself into an OUI fall of 2009. I have been compliant with the alcohol cles and the AA programs and paying probation. I was surrendered once by my probation officer because I missed one payment but I made it up before the hearing in front of the judge. So the judge dismissed it and my probation officer (I think) looked like a joke. Anyway my probation was scheduled to end 10/21 of this year... I owed a few hundred more dollars and I couldn't pay up. So I still went to the courthouse to see if I can get an extension but my probation officer left for the day and already issued another surrender notice. So I have until December 2nd to come up with the money I owe, which I will. But what will happen?? Is it highly likely I can I face jail time?? Will I be put on probation another year?? I don't have a record besides this and I am a fulltime student. I just want this to be over.
