Harold - Hackshield Bypass
1. First download the Harold's Hackshield bypass from the above link.
2. Exact the two files into your Combat Arms Hack shield folder. ( C:/Nexon/Combat Arms/HShield).
3. Rename the HSUpdate.exe located in the folder, I renamed it HSUpdate123.exe. ( C:/Nexon/Combat Arms/HShield).
4. Open the Hackshield Bypass located in the folder. ( C:/Nexon/Combat Arms/HShield).
5. Ignore the window that just opened and go back to the Combat Arms folder. ( C:/Nexon/Combat Arms).
6. Click on Combat Arms
7. Right after you click "Game Start" Click on the bypass. I like to push "Game Start" then push enter which will automatically click "Ok" on the bypass.
8. Enjoy I have yet to get an error doing it this way. This sceenshot was taking August 06, 2008 so this method should still work.
The method Harold told us rarely worked and I would get many errors, since I have been doing it this way it never failed and has worked every time for me and my friend.
Credit to Harold for making the Bypass.
