Has anyone else been experiencing bugs with the Quake 4 demo? And if so, are there any patches? I downloaded the latest 1.3 patch, but that must only be for the full version, as it didn't allow the demo to load... The demo doesn't load the first hanger level. It tries to load and then just returns to the main menu... I know I could just go out and buy the full version, but it would be nice to complete the demo... Any ideas?
