I'm using Mojave 10.14.5 which is supposed to be the latest version.
I'm sorry but I don't know what you mean when you ask if I'm using a "paid version". I purchased the TT cd from Costco and downloaded it to my Mac. The robo-voice did ask a question about whether I had the online or cd/download version and I responded with the latter choice. It then asked but did not "recognize" my phone number and redirected me back to Community Chat.
I have not tried the link you provided but will early tomorrow morning.
