A guilty verdict was likely entered in your absence and the judge entered a judgment and ordered you to pay court costs. That debt to the government will never go away and is likely being handled by the company that works for the government as a collection agency.
Too late to hire a lawyer, after the fact. Any defenses you had to the crime are waived, most likely, by your failure to appear or make a continuance request based on good cause.
I agree with Mr. Brinkmeier's answer. However, you may have the ability to still open the conviction up if it was taken on default. You should immediately hire an attorney to look into that option, but don't be surprised if it can't be done because too long a period of time has already gone by.
