Game Not Starting

[jens]

Have you installed any updates to the game? It should not ask for a serial number, so uninstall the game completely, make sure to also check Program Files and manually delete any Amnesia The Dark Descent folder that might be left there and also delete the My Documents/Amnesia/ folder. Then install the game fresh and see if that helps, possibly make sure to run the installer as an administrator.

There are no shortcuts pointing to shortcuts etc, the shortcuts point directly to the launcher.exe. And super_secret.rar is a bonus file you can unlock with the correct password.
