This is my injector, it looks better than the last one!
The default directory for Starting combat arms is (C:\Nexon\Combat Arms)
But if you installed combat arms somewhere this is what you should do:
(First check the change directory)Lets say you installed it on the desktop then just right click on the CombatArms.exeIcon and click on properties Next:
Copy where it says Location and just paste that on to the textbox and put start combat arms and it should work
