Puttygen unable to export key

Hi. Thanks for the Sunday reply :).

Right, just tried saving the private key from the PuTTy save dialog. Got a different error: "server refused our key". Have restarted SSH daemon on droplet.

Key looks like this

PuTTY-User-Key-File-2: ssh-rsa
Encryption: none
Comment: rsa-key-20140601
Public-Lines: 4
AAAAB3NzaC1yc2EE/tSY2c=. etc
Private-Lines: 8
AAAAgQC7WTuh6UCNbfRR1v5gYQZVQPB69+vG0tSf2acnyFtd75uweGGS/tAinS6a .etc
Private-MAC: 0069bc. etc

Anything jump out?
