I had Trados 2019 on my laptop and then upgraded to 2022. Trados 2019 stopped working for reasons I do not know but I didn't research it further as I wasn't using it. Now I have bought a new PC were I will install the 2022 version, so I want to use the 2019 version with my old laptop. I considered reinstalling it, but there is no license or activation code for this version! Do they expire?
