Reset completely the Sonata Recordings

Is there a way to reinstal sonata from the begining só it overwrite any configuration?
Our Sonara Recordings is not working, when we try to login we can insert the user ans password but only Error after that, we tryed to remove and reinstall, reset password doesnt work (the script show a DB Error), after that we tryed to rename the database and the /usr/share/sonata/recordings name só the instalation would create them again, but we still got the same errors, can you help us?
