Hex Editing for Hacks and Injectors(BASIC)

I changed 1 letter and save a file. But saved file has a new md5 checksum. Whatever, vinject start game with new dll file perfectly, but when I'm started a Battle and use some commands in dungeons, I see a window "Hackshield Error .... GameHack Detected d:\...\ConsoleHack.dll" What's wrong? It's a normal result? Or some one else have worked Console? Tell me please... (Im even dont run MHWalker.exe cuz expext the same error)
