It would be more helpful to your potential helpers here if you could show what inputs you provided to induce this error response. I realize you may think you have done that already by saying "When I open my database ...". However, it would be exceedingly strange for an application with a generic name like 'sqlitebrowser3' to be attempting creation of a normal (as opposed to system) table upon opening the database. Hence, I surmise that you have done something more than just opening the database.
