When starting directly, only black screen is shown with "LucasLib Assertion failed" dialog in the background. Selecting any option there (cancel, try again, ignore) doesn't change the situation.

The configuration tool does start, but crashed when selecting configuration options. Using this to start the game works, no mouse inputs work. I was only to able to press Esc and then Y to exit the game. Also the game audio shortly stops and gets choppy, everytime a mouse button is pressed.
