Problems with MW2 Liberation

Hey guys,

I have a problem with MW2 Liberation. I have extracted all the files from the archive on my desktop, but when I try to start the game as I enter my Steam account name + password, the game crashes. Is there a solution to the problem? Use MW2_Liberation 1.7

done use liberation
use choas or loaderX

Thanks ^^ I used LoaderX and it works.

thx bro
