OP provided me with a vouch copy of credentials I was able to use to login on the ExpressVPN website. Once logged in, it shows that the account is valid until September 1 of 2018. You can also see that auto-renewal of payment has been enabled.

As you can see, the activation code for ExpressVPN software (on my mac, as well as my phone) is provided. Once I downloaded the app to both my computer and device, I used the activation code in order to enable the VPN service. I used New York as my location.

I will state that I have successfully logged into Netflix using the US location of the VPN, and I am now accessing more movies that were not available to me using my regular IP address (as I live abroad in Central America). The subtitles no longer default to Spanish, either

I have also successfully been able to play an MMORPG that normally blocks free/limited versions of unpaid VPN accounts.
All is working as normal. I will update this thread weekly with status updates as to whether the account is still working or not, or I will post sooner if the account is disabled. I won't change the password that has been provided to me.
Stay tuned, folks!
(I have also updated my top-most post in this thread with the same information so that it is more visible to viewers)
