Thats the dll you must extract that to your desktop, then get a injector (EX. PerX) Or any Injector you want to use, then open the injector the process name put "Engine.exe" then go to browse (Thats for the dll) Then that Document (DLL File) you must select that, then turn on automatic injection and remember to turn of quit after injection or something like that. Then Right click on combat arms, go to File Location and go to Combat arms direct, then game start, The injector should inject the dll file into the game and when your at the login screen try pressing "Insert" And see if the menu pops up. Then just log into the game and have fun , Sry if i got bad grammer or whatever i was always bad at it.
