Game works on Windows 8 will not - no support, no e-mail reply

All Windows 8 owners should keep their hands off of this game! "Perry Rhodan" I bought as a normal DVD version in the media market. After installation, then the disappointment. It does not work - no matter what I try. In various Kompalibitätsmodi tasted old driver, nothing has worked. It's like a bad joke. At the time I had got the game borrowed from a friend, but it did not run on my old notebook with Windows XP, rather, it crashed again and again, the screen froze. Now I have a pretty fast notebook with gaming graphics card - and I've bought an extra in the game original, because my intro video liked it so much. But nothing works anymore. Too bad. I would have liked to play the game. But several inquiries by e-mail went unanswered. Poor support.
