here is the exact error to my earlier post. hope it helps someone to advise me on what I should do. " invoices_.fp5 is damaged and cannot be opened. use recover command to recover this file." Then I try to use the recover command and it gives this error. " this command can not be found or has been deleted"
it sounds as if you might need to re-install optigold. It's not as daunting as it sounds just make sure that you backup all of your database files first.
