Send in the request for a hearing tomorrow. The rmv usually leaves a few days window for mailing and whatnot. In the event you receive a suspension notice for nonpayment, go to an rmv with a hearings officer and let them know you sent in the appeal. They can manually enter in your request.if you would like to consult on the details of the ticket feel free to contact my office.
You can send in the notice for a hearing and see what they will do. If they deny you a hearing you can appeal to the clerk magistrate of the court where the hearing is too take place. If you can show a valid reason the clerk may still give you a hearing. At that time the clerk's office would notify the RMV and they would mark it up for a hearing. In the past I had sucess with appealing old and even paid tickets. It can be done.
