Answer 1

What package protection level are you using? Don't Save Sensitive? Encrypt Sensitive with User Key? I'd recommend changing it to use Encrypt Sensitive with Password and enter a password. The password won't disappear.

Have you tried testing the connection to the database in the connection manager?
