Divine Will and I have come up with this neat little program.
Here's how it works:
1: Make a "Update2" folder inside you HShield folder. (C:\Nexon\Combat Arms\HShield)
2: Start Combat Arms
3: Press Game Start
DO NOT LOGIN YET.
4: Run the .bat file inside the .rar archive.
5: Login to CA
6: Win
--------------------------------------
VERY IMPORTANT:
When done playing Combat Arms, run the .bat file once again!
