Here it starts fine. Only DLC is not working/blocked. Annoyed as hell.

Hi, Zauberstaubix! I apologize for the problems with the game
May I ask you please to send game log files from .log folder (located in the game folder) to email tinaynox@gmail.com?
You can reach game folder by RMB click on the game in Steam library and select "Installed Files/Browse..." option
In some cases these logs can be located in user documents folder: C:\users\<username>\Documents\Space Pressure 3D - Prelude\

Same for me. game does not start

Doesn't start without any messages? One player here said that reinstalling OpenAL library helped him in this case:

Yes, starting via steam, no start. Starting from .exe, launch normally.
