Due to the heavy load on Steam while releasing patch 1.1, some players might experience problems with the game, including crashing or being unable to start the game.
In order to fix this, please repair the game files following these steps:
- Restart your computer and launch Steam
- Enter The Medium's page and select Manage > Properties.
- Select the Local files tab and click the Verify integrity of game files... button.
- Steam will verify the game's files - this process may take several minutes.
