I am a lawyer in CT and practice in this area of the law.  If your probation required you to pay the fees and do the comm service and you have failed to do it there is a chance of you being found in violation of probation and being locked up.  I would consult with your atty on this as I would need to see the probation orders to make a definitive conclusion here.  Maybe there is something you can do but i would need to speak with your parole officer and se the terms of probation.  Again, i would speak to a lawyer that can do this in TX.
