You should call your lawyer and probation officer and ask this question. Even if some how probation discharged you (you need a court order saying so) from probation you could still have problems. Such as the loss of your right to drive. Take with your lawyer!

Well you can have a problem in court. You have had two years to pay this! But, if you have had no or very little income you perhaps can get a bit of understanding from the court. If you do not have a lawyer ask that the court to give you a Public Defender to help with this matter.
