problem with system.mrs files

hi, when i download and change any system.mrs hack, gunZ doesn't start , the login is blocked with the message "cannot access to the server" , if i put the original system.mrs, game start and log on as normally i play.
now, is my problem or the hacks works , cause i use gunz.exe and system file don't change by updates or other instances. :cry:
