Key not activated in game

[norbert]

I am trying to play the Windows version of DLC via Proton on Linux. I activated the DLC with my key, but the loading screen tells me "Buy DLC Crash" ... clicking there brings me to steam store which tells me that the item is already purchased.

Could you please
- make the key working also in the Windows version played on Linux via Proton
- or better fix the errors with DLC on Linux not starting

Thanks

Hm, can the game in proton not communicate with Steam?

On Steam did you go into the Betas tab and opt into testing?

[norbert]

Yes on activating testing. And after the update today it works. Thanks
