A temporary fix for the issue until SE fix the Steam Overlay integration that is causing this

1. Launch the game through Steam
2. Log-in with your account details, but DO NOT press the Play button
3. While the launcher is on the screen where you can see the Play button, launch the Task Manager, and end the Steam process
4. After Steam has been forcibly closed, press Play
5. The game should work as normal

fact is ...after that steamoverlayupdate thingy from SE the game wont start propertly,..but it affects only a certan type of steam players...for example three membs of my fc have no problems...for me the game only works if i use the methode above...
