What was the error? We will try to fix issues that prevent people from playing, if we can, we will upload a build that you can download that has critical bug fixes.
Error was "The procedure entry point CreateDXGIFactory2 could not be located in the dynamic link library dxgi.dll". I've had similar errors with Unreal before (with DXGIGetDebugInterface1) which I think are to do with the fact I'm on Windows 7 (though they don't usually stop the game from running). Based on everyone else's positive feedback though, I seem to be the exception not the rule, so I wouldn't worry about it. =)
