I did a quick check of Florida laws, and was surprised to find that there is no statute of limitations on a VOP. This would be a technical violation. There are many atty's that offer no/low cost consults to get you started in the right direction.
Although you may no longer have receipts from that time showing payment of same, is it possible that you still have your court paperwork (most specifically, your last court order releasing you from probation showing that you did follow all the conditions and are now finished)?
