i was on probation for a misdemeanor, I paid while on probation ,unknown to me, there still is a balnce owed, lein if not paid

My probation officer never told me i would still have to pay after i got off probation, now after 6 months they sent me a letter saying I owe 2000 dollars due to interest it was only 650. Will I be denied at my socila hearing that Ive been waiting for , for 5 years, because of this outstanding bill that could damper any assets I accumulate inb the future due to a probable pein they "say" they "could" put on me? I heard this one teenage boy got a misdemeanor for a possesion of marijuana charge and he never paid it and when he applied for social they denied him because he owed the courts. How are you supposed to pay these types of bills when you cannot work, and /or why would they not approve you so you can start paying your bills. For 5 years Ive barely made it to eat, let alone pay off a 2000 bill with 75 percent ofit being interest. Would they really denie me of disability because of this? What if I started making payment arrangements with them and was cooperative when my hearing comes up in december of 2011? Thank you...Sondra
