Hi @Kulturnilpferd,
Thanks for sharing to our community!
Please note that users like yourself, who purchased the previous version of djay Pro from the Microsoft App Store, can still download that (now considered) legacy version of the app.
All you need to do is find the app in your purchase history list via the app store and redownload the program. We recommend you follow the guide below by HowToGeek to get you started.
Additionally, I’d like to mention that we do have a free legacy upgrade for users who purchased the last version of djay Pro. Please see the FAQ below on that topic for more info.
Have a nice day!
