I'm pretty new to this stuff and I'm not real intuitive. I boot up the wad for ultimate doom. When it loads I try to select a new game but I can't select any of the options. I can see the options and I can hover over them, but I can't select any. The triangle in the top said there was a 0.5<=view-cross-width<=5 error and of course I have no idea what that is. So now I'm here asking for help.
