I have been trying to play this games for months and posted my bug in the bug page but no one answered me. When I start my game it just goes to a black screen. I hear sound but the screen is black. I am assuming it's a resolution problem but there is no config file I can find. I uninstalled - re-installed multiple times over the last few months hoping the problem would fix, but to no avail. I want to play this with my kid, but its just won't work. The funny thing is that the first time I started it it worked fine, but it has never worked again.
