The game hangs when boarding technique (Farming Simulator 15)

I have a problem. When you get into technique, I have the game hangs and does not respond. But there are sounds cards , despicere task says that the application is not responding. No mods were not installed, it started by itself, before it worked perfectly. Game reinstalled, did not help, and Windu was perenasytil twice, did not help, I think at least you will be able to give advice.
