How to update licensing? Where are my keys?

I am taking over this website from a previous Editor in Chief, and I have paid to renew lapsed licenses for Pro and Custom Category Settings and Publisher Bonus. I would like to get these plugins updated and working, but I’m at the moment very confused.

In looking through support, I noticed that I could “deactivate and then re activate” my licenses to force a refresh. I deactivated Publisher Bonus, expecting some UX to be able to reactivate, but it just disappeared from the list of activated plugins.

Also, although I was able to successfully update all of the plugins and add-ons, I am still showing that the remaining addons (Pro and Custom Category Settings) are not renewed, and I am getting a WordPress message bar that Pro needs updating, even though it is on the latest version (1.7.9.3)

Since I am taking over this site, I do not have access to the original license keys (apparently), which it look like I need to re activate Publisher Bonus.

How can I ensure that this site is up to date and running Post Pay Counter correctly? How can I get the license keys?
(you can contact me directly with keys kip *at* onmsft *dot* com).

From all appearances I think everything is working correctly, but I don’t want to mess up our writers’ payments!

Thanks
