1. Navigate to the folder where your copy of 'MapleStory' is installed. By default, it is in the 'Program Files' folder on the root of your boot drive.
2. Open the 'HShield' folder located inside your 'Maplestory' folder. double-click the file named 'HSUpdate.exe.' This will manually start the Hackshield updater that can fix the program if any error is preventing it from starting.

3. Start the 'Internet Explorer' browser and click the 'Tools' button at the top of the menu bar. Click the 'Work Offline' button if there is a green check mark next to it to uncheck it. 'MapleStory' and Hackshield connect to the Internet via Internet Explorer (even if you use another browser like Firefox), and having it set to 'offline' mode will cause errors.
4. Type a description of your exact problems with Hackshield in the pop-up window that appears when the program crashes. The details must go in the 'Describe The Problem' section and your e-mail in the smaller section below it. Click the 'Run AhnReport' button to automatically save the error log files and email it to the creators of Hackshield for analysis. This is a last resort to fix Hackshield and should be done only if the previous steps did not rectify the problem.
