Sued a Auto Shop whom worked on my vehicle without a license. Lost but want to appeal with lawyer?

What should I do? I took my vehicle to auto shop whom worked on my car without a license. Shop had ruined my car and told me to get out, not to come back. I took him to court and I lost! I tried calling the court house and left messages for the advisory dept but no response. Its now been over a year, I went to the court house and asked why and how could I of lost. Advisory dept told me it was because I sued the owner not the business! Adviser said I cant do anything Is this true?
