What does "This Mac already has a vault" mean?
Short answer: A Mac connects to one Delta Trust vault at a time, and this one already has a vault. Enter another vault's kit to reconnect, or remove the current one first.
This Mac is already connected to a Delta Trust vault, and a Mac can only be connected to one at a time. That's why you can't create another here.
If you meant to connect a different, existing vault, enter that vault's recovery kit. If you really want to start over, remove the current vault from this Mac first.
