Dear honourable X-Planers,
as stated above, X-Plane 11 wants an activation key when launching a flight. Since I use the Steam version, I (obviously) dont have any key and hence, can not use the software anymore. Funny enough, I already used it for almost 100h without problems, so the activation key prompt just appeared literally over night.
- Verifying the file integrity via Steam,
- completely uninstalling and reinstalling it and
- deleting th DRM-files in the AppData\Local\ folder
had absolutely no effect. Still can not use what I paid. Help would be highly appreciated.
