Pro Tools free trial and Catalina

[AlpD]

Dear Friends,

I am returning to PT from version 8 (and to music making after a few years) and I wanted to dust off some older ideas. Unfortunately my old Win laptop is almost dead (and stopped running PT at some point). I now have MacBook and I wanted first of all to try to open those sessions and perhaps export them to AAFs to some iPad app likr Auria for on the go editing. I downloaded the PT trial but it is not running - of course I forgot how it is with DAWs and updates and my Mac is already on Catalina. The trial file is with previous version (2019.10 I think) and will not run. Also, I don’t see any option to upgrade it to 2019.12 which should run. Can anyone help with this? Is it just a matter of time when the trial file is switched for the newest version? Thanks in advance!
