What can I do about my previous eviction?

I moved into an apartment back in September 2008. I stayed in this apartment at $435 a month with all utilities included. In early November 2008 I lost my job due to missing about 2 days a week for my Asthma. My landlord offered me a job as Maintenance Crew paid under the table. In December 2008, I changed to a bigger apartment at the same rate. I never signed anything stating the transfer. I only had my lease for the original apartment. In January 2009, I was unable to pay rent due to the landlord letting me go because, “He couldn’t afford to pay me.” I received a 3 day notice to pay up or move out. I couldn’t pay the rent or even borrow the money to. I couldn’t move since I had an entire 1 bedroom apartment and no car or place to store my stuff. I stayed and no legal actions were taken. I received another notice in February 2009 for 3 days. Once again, I stayed and was unable to arrange storage or moving. This whole time I was looking for employment. I was then served a subpeona for eviction. I showed up to the court on the date and had time to speak with the leasing agent and the landlord’s lawyer. We agreed to a date I had to be out by. We proceeded with the hearing and it was filed for the eviction on March 31, 2009. No payment was due according to the judgement. I had moved out by March 31, 2009 and had turned in the keys. Now 10 months later I have a full time job and trying to rent a new apartment through a different company. Issue is that I have the past eviction. They sent a form to the previous leasing agent, and it was returned. The new apartment will not allow me to rent, because the previous landlord stated that I owe $665.00. I have not been informed of this debt and the complex has had my contact information this whole time. What can I or should I do?
PS
I can not find the documentation of the hearing. I plan on contacting the previous landlord to see if they could make a copy of their document for me. Any advice on how to obtain it another way?
Found an apartment, though its not exactly what I was looking for. Just had to find a landlord that just wanted their security deposit and first month right away. Thanks guys.
