If the hack is CTDing you then restart your computer and don't use it.
You are probably trying to use Windowed Mode.
Crashing To Desktop
Anyways, try restarting like I said and try to run combat arms after restart, if it still crashes then they won't work for you.
Did you restart? I know it sounds too simple but a lot of the time when this sort of thing happens it's because of some change in the CA files and restarting seems to fix it. If that doesn't work you may have to reinstall.
well....
put the unpatchabel hack in ur ca folder or else it wont work.
than click on it and put everything on
than press play and open combat arms
go in game and the unpatchabel hack should work
