I also have the same problem. I launch the game but that's about all I can do. I see the intro but there's no way to actually start the game. Anyone have the same problem and found a way around ?
I tried checking the files integrity, I uninstalled and reinstalled but still all I can see is the intro. There's is no start button, no menu at all. Whatever I press on my keyboard or mouse click the intro just keep playing.

same problem like wtf eaven tryed changing my pc to english and it dosent work only a looping menu video with no play button

SAME.

I've just bought the game and I can't even start it due to the intro loop.

Tengine debugger console (the one which pops up when you press M) is showing a bunch of fatal errors:

DEVELOPER, FIX IT PLEASE

Hi i have same problem only intro and cannot play :-(

i havent start icon like this: https://www.youtube.com/watch?v=29ExS2zuILQ only small text left down corner

What worked for me was changing Windows language to English.

As I see, the developers don't support this game anymore, even if you bought it on the first day of release. And still a lot of people have a problem with the video looping on startup. As I see it, the solution still doesn't exist. So we can only hope they fix it while we're still alive :D Have a nice day.
