It should be simple to fix, as long as no money is owed to the state; but the problem is that without knowing what went wrong it's hard to know what to do to fix the problem.
There's a joke about a mechanic who retires, then is called back to work because a very expensive machine broke down and nobody can figure out how to fix it. He tells them it will cost them $10,000. When he goes into the workplace, he goes up to the machine, takes a hammer, taps a particular point on the machine, and it starts to work. Management balks at paying his fee and asks for a bill. His bill reads, "Hitting machine with a hammer, $5. Knowing where to hit the machine, $9,995."
I'm not saying that it should cost you $9,995 to figure out what went wrong -- just that when you do pinpoint the problem this may turn out to be an easy question to answer, but without access to the court records or the child support records it's really difficult to give you useful suggestions.
