Create a new database. Check its references. Observe there are 4. Those 4 should always be there and you should leave them alone. Select them for your database as well, and put them in the correct order.
Beyond that, I see:
Dim db as DAO.Database1_be
Database1_be is not an Object in the DAO library. "Database" is. So this should be:
Dim db as DAO.Database
