Harassment suit expungement

I recently took my ex (my son's father) to court last May for non-payment of child support as he wasn't paying anything. We had a follow up hearing in June & September. He failed to show up in Sept so they issued a capias. He was not found until the end of January 2011. He is in arrears of over $4,000. When we went before the judge, she said he would have to pay me $750 that day along with the $350 for the constable fees or serve 45 days in jail. He was unable to come up with the money and was sent to jail. The next day I started receiving harassing emails from his wife saying that she wishes I had had an abortion, that my son didn't exist and that her & his father want nothing to do with him. I emailed her back and although the emails were vulgar there was never any threat of physical violence. I asked her to meet me in public instead of talking through emails. She said "sure, no problem, I would love to meet you, I'm not scared of you". That never happened so I eventually blocked her from emailing me any further. Then, 19 days later, 2 days before my ex's review hearing to see if he will get out of jail or go back, she files a harassment suit on me (she never contact the police) claiming I threatened to smash her face in, that I called her constantly and that she is so scared of me & thinks I'm stalking her. Her belief was, that if she had the harassment order on me, I wouldn't be able to go to the review hearing and her husband would be free. I'm the plaintiff so I was told I can be there regardless of the order. She started yelling at the court officer on the day of the review hearing saying that I couldn't be there because I was harassing her & I had to stay 100 yds away from her. She was told it's not her case, it's mine and I have every right to be there. She then started yelling saying she was "taking me to trial" At the 10 day hearing for the harassment issue, the judge read over the affidavit & my motion to vacate (that I filed the day I received the order) along with my evidence. She was not able to produce any phone records or emails showing the threats. I however was able to show emails from both her and I showing the conversations and how she committed fraud on the court and perjury in order to obtain this emergency order as there. I also had my phone records. The judge vacated the motion. I contacted the Commissioner of Probation to see if I could get this expunged. I was told that I would have to prove fraud on the court in order to do this. I have all emails showing that what she said wasn't true and requested the harassment order illegally. I can't afford an attorney so I'm looking for help on how to get this done. I know I need to file a motion to expunge and was told to ask for a 30 day hearing so that the Commissioner of Probation could review the file as they are the keeper of the records. I wanted to know if I could subpoena the person who put the harassment order on me requesting that she bring in evidence of my harassing emails & her phone records showing I called her? I never called her nor did I ever threaten her so I know she will not be able to produce them but this would be my way of helping myself to prove that she commited fraud and perjury. Would this help my case along with the evidence I have? I have no record, until now, and although it's a civil issue I still want it cleaned and not destroyed for a revenge issue. Any assistance is greatly appreciated. Thank you for taking the time to read this monstrosity of an email.
