Send a certified letter to the court in question, documenting in chronological order, with supporting evidence, indicating the chain of events that caused your delay in addressing the citation. Or, you can contact an attorney, who will contact the prosecuting attorney and work out a deal.
Otherwise, as mentioned by Creeker, your driver's license will be suspended (may already have been done) and you will have to pay all fines, plus a reinstatement fee, to get everything back in order.
Since you sent in a check, this should work in your favor instead of someone who just blows the whole thing off.
If I were you, I would contact an attorney who might be able to work this out in your favor with a letter or short phone call.
