Hello,
So my problem is that i cant update the game it just says that it cant find the game. Have bought it over download, have it on my stationary computer and it always worked fine. Then my son wanted to paly it since we buyed an laptop. But I cant get those patches to work. Has search the internet for answears and tested with updated directx and so on but nothing works.
Have version 1.022.1, and on my another comuter it worked fine and it was bought from same place. So why in the ninth hells cant i update the game?
Please help me before i get mad.
