Erro na connection do SQLite

Android

Delphi

11/01/2018

Fala galera, blz!?
Estou fazendo um app simples, mas que precisa de um banco de dados no app. Estou tentando colocar o SQLite, mas venho enfrentando muitos problemas.
Continuo recebendo erro na connection:

 "Invalid class typecast"


Usei o SQLite studio e as tabelas estão todas certinhas! Nos detalhes do erro tem as seguintes mensagens:
