A few things to try. You might try a log out and then a reboot of the PC and/or device, and a log back into the Spotify App and see if the content will play now. A good way to check if it is an app installation issue or a possible cache corruption issue is to try to play the content from the webplayer: https://player.spotify.com/ if the content is playing fine from the webplayer but not from a device app, a clean reinstall might be needed to try to clear this up. Also can you post what device, OS, and also Spotify app version you currently have that this issue is happening with?
I checked all three of those releases, and they are currently available to Germany Spotify users. Have you tried going to another PC or system outside of your Local Network, and logging into your Spotify that way and see if the content will play? Usually when all Spotify apps that use the same network, this kind of issue can arise. Is there any differences getting this content to play using Wifi or Cat5 connection to a PC? Are you getting any kind of error codes or warnings about the playback of this content? Also what is your ISP provider, so I can escalate this thread with all important information? Also you might consider including what region of Germany you are using the Spotify service in, but if you wish not to provide this in a post just say so, and a Spotify mod can get this from you in a PM if it is needed? Just getting enough information so when a Spotify mod looks at this thread, they can send everything along to be looked into.
