Jasper on "[Plugin: Postman SMTP Mailer/Email Log] Email Log doesn't show up after upgrade"

I have two sites on the same host with the same setup on which I installed Postman SMTP at the same time.

One has been upgraded to 1.6.9 - the email log tool used to work, and now it doesn't show up as an option under "tools" any longer.

Also on the dashboard, where it says;
"Postman is configured and has delivered 3 emails.

Postman will send mail via SMTP-STARTTLS to XXXX:587 using Password (Plain) authentication.

Email Log | Settings" <-- Email Log can't be clicked on, but Settings can.

The other site is on 1.6.6 and the email log is still accessible.

Thanks so much for your help.
