My question involves criminal records for the state of: Ohio

What happened was when I was 18 my friends and I where out driving, there was 4 of us all together in my car. My one friend was however was 17 at the time a few months away from being 18. What happened is he hit a mail box and drove around for a bit after. We where then pulled over and I the owner of the car was arrested along with him. I went into court I asked them about my record they told me there would be nothing on there. Then about 8 years later I applied for a job and was told I have I will start on in so many weeks. Then a week before I was suppose to start work I got a call, and a letter that we wouldn't be able to proceed because of a misdemeanor on my record. To my shock I had to do a background check on myself. I then found I was denied other jobs due to this misdemeanor. So about 6 months had passed and I went to expunge it. I don't understand how all this law stuff works completely some in ends and outs. I thought I got this misdemeanor because I was the owner of the car. Any who I got a letter back from the court that they had expunged it and said I should have never ever been given this misdemeanor in the first place.

So my question is... Can I sue the court system due to lost compensation over the years, due to me not getting jobs. I do have it in writing from companies why I was denied and due to the mistake the court made. I found out I lost out on a lot of good jobs due to this. And these where close to 90 thousand a year jobs too.

Any help or pointers are appreciated. Also the only thing I have on my record is a few speeding tickets as of the current moment.
