Run Steam Update after a Sandstorm server patch or when players receive a version mismatch.
- Create a backup, then stop the server.
- Click Steam Update.

- Wait for the update task to finish before starting the service.
- Update Sandstorm through Steam on each player's computer before reconnecting.
If the server does not start afterwards, confirm that a command line is selected and check the latest Insurgency.log before reinstalling anything.
