Bonfire 2 login problem

I can no longer log in.

Installed Bonfire 2 in CI 4.3.2. Everything was working fine. There is one user, the original SuperAdmin.

Then, in Bonfire settings, I activated require email confirmation of new registration.

Now I can't log in. Message says: "You must activate your account before logging in." I didn't receive an activation email. 

I'm assuming the problem is that SuperAdmin account needs to be activated, but no activation email has been sent. 

Is that the problem? What next?

Thanks!
