The game works as it should but when i hold a button longer than 1 second the game freezes. When i release the button the game works as it should. I recognized it's only when i play with my keyboard. The mouse works fine. I also tried to play it with a ps3 controller - also works fine.
And the keyboard itself is also not the problem, i plugged in an other keyboard - same problem.
So the problem is i can't walk or do anything where i have to hold buttons!
