Multiplayer DLC and crash

So, i've playerd over 50+h without any issues till now.

Today i've see that a new free-dlc for multiplayer was aviable. I've downloaded it and now i can't launch the game in fullscreen mode... The game crashes after a few seconds with a dx error (the same error that a lot of people already have experied). The only workaround seems to play in windowed mode...

Does anybody have the same issue after the release of this dlc?
