Can't play just crashes

So when I open the game, it goes to the screen i click online takes a sec, goes to lobby.. but the moment i join some1 or i go to solo play it gives me stuff like EXE_UI_ERROR 23564 and stuff... Whats the fix to this?
I believe this happenes by using pirated version of the game and or pirated dlc. This used to happen to me before I got the steam dlc from my account.
