Either hire an attorney, or ask the court clerk to put your case on calendar and take your chances with the judge.
Traffic tickets are like cancer; if you ignore them, they don't go away, they get worse.
What would have been an inexpensive problem to resolve has probably turned into an expensive fine, and you'll keep getting arrested until you take care of business.
This is NOT legal advice. It is a general discussion of legal principles by a California lawyer, and does not create an attorney/client relationship. You should always consult PRIVATELY with an attorney.
Do you have a valid license now? That will help your chances a lot. From what you describe it looks like the officer gave you a new court date to appear for the 2011 case. You can go to court on that date to resolve it or because it is still in warrant status now, you can probably go in earlier to quash it as well. You probably will have a better chance with an attorney and you will have to resolve whatever new ticket the officer gave you in addition to the old one.
