I just had this problem too, but even after creating the second droplet all it did was send me the first email that never seemed to arrive without following up with a second email. So the password form the first email fails in the second droplet. Is this something that happens regularly?
I too experienced this problem with initial creation of the droplet. However, resetting the droplet's root password triggered the email.
Until the issue is fixed, try this:
Check your email, you should have received the access password. At least I did.
