Cannot download the Passolo SDLX add-in.

Hi. I cannot download the Passolo SDLX add-in. Die Fehlermeldung lautet: Download not avaliable. You have logged in successfully, however this app is not available for you to download because you don’t have a license for one of the supported products (SDL Passolo 2015 - SDL Passolo 2016 - Passolo 2018) in your account. What cam I do?
