I'm not sure if this should be in the technical forum. Please move it if it's in the wrong place.
I wasn't able to download BJ4 from the games page, the link was dead, so I downloaded it from grundislav's website. When I unzipped it and tried to run the game I got this message:

I'm wondering if the error was something to do with file paths rather than the game itself, because all of the html manual files were looking for images in a folder that doesn't exist on my computer, presumably the location they were in on the author's machine.
