The configuration program's test can have a problem with some video card and driver combinations, resulting in a black screen, but the game itself should be fine if you check the 'skip test' box.
A couple people had problems with the game creating the configuration files, but if they already existed the game would load fine. I previously gave a
download link for my files, but I don't know if they would help with the German version of the game. If you have access to another computer you could try installing it there, start it, exit and copy the configuration files to your computer.
In Windows Explorer, if you browse to the '
..\Beyond Divinity\Static' folder, you can rename the '
intro.mpg' video. This will prevent the intro video from being played each time the game is started, and has helped with crash problems that were related to switching resolutions.
If you have not done so already, you could try emailing support@larian.com, with a description of the problem and maybe a link to this topic.
