First open your injector in the inject too slot Type Engine.exe
Second go to settings for your injector and put a check in box that says Auto inject on open and another check in the box that says close after injection.
thrid add the hack file to the injectors list of files to inject.
Now open combat arms login and hack
If you get disconected after that either your hack is patched or your injector is patched.
If this helped you then thank me,
