Based on the message, your program probably uses Devrace's FIBPlus components and it is not asking you to make a new database but is informing you that the transaction can not be started because connection to the database is not opened.

In short, this is a bug that your application (PrimaDent) vendor made and the only thing you can do is contact them and report a bug.
