The game won't start
If the game won't start (or starts and ends immediately) you may try these options:
The game may be blocked by your antivirus. For example, many users of Avast noticed that the game was blocked by Avast without any notification. Attempt to disable your antivirus, reinstall the game and try again to play. If the problem is resolved configure your antivirus so it will not scan the game's folder again.
