Is there a way ro reload Sonar exactly as if it was the first itme I installed it

 

Hi, I am trying to reinstall Sonar the same way it was before I misplaced Folders etc... I just want Sonar to forget it was ever in my computer. I have tried many things but there seems to be a folder that keeps my setup alive even if I try to delete everything, and once I reinstall Sonar I go back to exatly the same state it was... I want Sonar as it was with factory preset... How can I do that?
 
Thanks!
