Okay! nach dem kontaktieren mit Feral Interactive bekam ich eine E-Mail mit diesem Inhalt:
Dear Customer,
We are sorry to hear that you are experiencing a problem in Tomb Raider Underworld.
We believe that the reason you are seeing this error is that an unusual set of preferences has been created.
Please delete the Preferences Data file in order to reset the preferences. This can be found via the Open Preferences Folder button on the Advanced tab of the pre-game options window.
Please be sure to only delete the Preferences Data file and not the entire folder as this will also delete your saved games
Once the Preferences Data file is deleted, please launch the game again and you should find the issue resolved. Please let us know how you get on.
Best Regards,
GerardEs hat funktioniert!
