Hey same here I get to the loading screen and closes on me!
My friend has same Win 7 64 bit and works perfectly..
At The Moment im just re-downloading the game because sometimes when patching some files might not have transfered correctly...
Try re-downloading it and we will see how it works..
Good Luck To Both of us and especially to you since it seems you like Combat Arms that much much you had to start a new thread.
Im done writing stuff now...
